LASER TARGET PRACTICE SYSTEM, METHOD AND APPARATUS
Laser target practice using an ultra-violet light emitting laser that is pulsed on when a weapon trigger is pulled. The UV laser light pulse illuminates a spot on a target having a coating of phosphorescent material on a face thereof. The phosphorescent material within the illuminated spot glows for a certain time thereby visually indicating a location of the spot on the target. The UV laser light pulse may also illuminate a spot on a target having a photochromic paint coatings on a face thereof. The photochromic paint coatings within the illuminated spot changes color thereby indicating a location of the spot on the target.
This application is a continuation-in-part of and claims priority to commonly owned Pub. No.: US 2013/0122471 A1; Ser. No. 13/295,946; filed Nov. 14, 2011, entitled “Laser Target Practice System, Method and Apparatus,” by Randy Yach and Paul Katz, and is hereby incorporated by reference herein for all purposes.
TECHNICAL FIELDThe present disclosure relates to target practice with a rifle, shotgun or handgun, e.g., pistol or revolver, and more particularly, to target practice using an ultra-violet (UV) laser apparatus in combination with the rifle, shotgun or handgun, and a phosphorescent material and/or photochromic paint coated target.
BACKGROUNDProficiency with a weapon, e.g., rifle, shotgun, pistol or revolver, requires practice. Learning how to properly aim and accurately shoot the weapon at a target is a major component of obtaining proficiency with the weapon. Budgetary and time constraints, however, limit how often one can go to a shooting range and shoot live ammunition. To compensate for a lack of live ammunition training at the shooting range, electronic target training that simulates the impact of a bullet on a target with laser light is often used. Laser light target practice training saves time, money and live ammunition, while providing for maintaining shooting accuracy and proficiency, e.g., unsighted fire, accuracy, grouping and trigger control. Laser light target shooting provides for more frequent target practice, thereby enabling a more confident shooter who can enjoy the benefit of low-cost target training at any location without restriction or concern for gun fire noise bothering neighbors or worrying about the safety of where a fired live round may penetrate.
Existing laser light target practice devices use a visible red or green wavelength laser that is activated by a firing pin of the weapon striking a pressure or displacement switch, or a sound activated switch that turns on the laser from the sound of a hammer striking the firing pin. Either way, based upon the aim of the individual, a brief pulse of laser light paints a target with a visible spot of light where a live round would have hit the target. One company has even introduced a laser trainer target that records (saves locations) electronically when a laser light beam hits the target each time the trigger is pulled by detecting the laser light point with a plurality of photo detectors arranged in a matrix on the target. Then after the laser target practice session is finished, the electronic target can display all of the laser light hits on a light emitting diode (LED) matrix on the target.
The laser generates a pulse of light each time the trigger is pulled, but when using a paper target the visible laser light pulse on the paper target is of very short duration and is easily missed in combat or police training simulations. The electronic target is better at displaying all laser light hits, but does not show these hits in real time, rather the shooter must wait until the target practice round is over before activating the electronic target LED display that then shows the laser light hits stored in a memory of the electronic target.

A more complete understanding of the present disclosure may be acquired by referring to the following description taken in conjunction with the accompanying drawings wherein:
While the present disclosure is susceptible to various modifications and alternative forms, specific example embodiments thereof have been shown in the drawings and are herein described in detail. It should be understood, however, that the description herein of specific example embodiments is not intended to limit the disclosure to the particular forms disclosed herein, but on the contrary, this disclosure is to cover all modifications and equivalents as defined by the appended claims.
DETAILED DESCRIPTIONPhosphorescence is a specific type of photoluminescence related to fluorescence. Unlike fluorescence, a phosphorescent material does not immediately re-emit the radiation it absorbs. The slower time scales of the re-emission are associated with “forbidden” energy state transitions in quantum mechanics. As these transitions occur very slowly in certain materials, absorbed radiation may be re-emitted at a lower intensity for up to several hours after the original excitation. Commonly seen examples of phosphorescent materials are the glow-in-the-dark toys, paint, and clock dials that glow for some time after being charged with a bright light such as in any normal reading or room light. Typically the glowing then slowly fades out within minutes (or up to a few hours) in a dark room. The phosphorescent material when excited by light energy of the appropriate wavelength, e.g., ultra violet (UV), near ultra violet, blue light, etc., will glow for an extended period of time after the light energy excitation ceases. When only a small area of the phosphorescent material is illuminated by a sharply defined coherent light source, e.g., laser light, only that small area will glow and the surrounding areas will not.
Referring now to the drawings, the details of specific example embodiments are schematically illustrated. Like elements in the drawings will be represented by like numbers, and similar elements will be represented by like numbers with a different lower case letter suffix.

There are various phosphorescent material types having different persistence and/or colors that are easy to see and remain visible for a sufficient time to observe the accuracy of the shot(s) and allow instant shot placement feedback to the shooter. If photochromic paint is used in place of or in addition to the phosphorescent material coating, a permanent or semi-permanent record of the laser shot placement may be achieved. Pulse width of the UV laser may be adjusted for a desired phosphoresce (excitation) of the spot 410. An advantage of the present invention is that a minimum pulse width of the UV laser may be used, only long enough to excite the phosphorescent material, which will conserve battery life of the fire training laser. It is contemplated and within the scope of this disclosure that any of the fire training lasers shown in
Photochromic paints and coatings contain dyes that change conformation when the film is exposed to UV light, and so they change color. Depending on the composition of the color changing paint, these pigments are either irreversible or they will eventually return to their original color. Dye and chemical formulas used in photochromic paints begin in a clear state, and adopt other pigments because of molecular changes that occur when the compound is exposed to heat or ultraviolet (UV) light/radiation. Manufacturers can make these paints reversible or irreversible.
Referring to
If the phosphorescent material coated target 408 (or photochromic paint coated target) is used in direct sunlight, the UV light component from the sunlight may cause the phosphorescent material coating to slightly phosphoresce. Normally the UV laser light illumination of a spot on the target is of a much greater intensity then any background UV light. However, if background UV light is a problem a simple shade or “awning” may be used above and to the sides of the target such that an “ambient light shadow” is cast over the target. Since the face of the target is what is being aimed at, the shade or awning over and around the target face will not interfere with the target practice, and may also help the shooter to easily see the glowing phosphorescent material spots (representing shot hits) on the face of the target in bright ambient light conditions, e.g., sunlight or over lighted indoor shooting range.

Referring to
Other embodiments may comprise using phosphorescent material coatings in single or multiple colors on silhouettes, figures, and 3D targets. UV based lasers include wavelengths from about 100 nanometers (nm) to about 400 nm. Near UV or “blue light” lasers include wavelengths from about 360 nm to about 480 nm. Use of both UV and near UV light lasers is contemplated herein and any term herein referring to “UV” also includes “near UV.” A near UV 405 nm laser works well and is readily available at a reasonable cost. The shorter the wavelength of the UV laser used to excite the phosphorescent material coating, the brighter will the phosphorescent material glow. Also, using a shorter wavelength will make the UV laser beam harder to see and only the shot location will be visible, e.g., glowing phosphorescent material.
While embodiments of this disclosure have been depicted, described, and are defined by reference to example embodiments of the disclosure, such references do not imply a limitation on the disclosure, and no such limitation is to be inferred. The subject matter disclosed is capable of considerable modification, alteration, and equivalents in form and function, as will occur to those ordinarily skilled in the pertinent art and having the benefit of this disclosure. The depicted and described embodiments of this disclosure are examples only, and are not exhaustive of the scope of the disclosure.
