Patent number: 5363559Abstract: A telescope inner tube locking device and method for positively locking the telescope inner tube in it's previously aligned position. The locking is accomplished by using a biased locking screw which operates to apply a force against the inner tube of the telescope while the windage and elevation adjustment screws on the telescope are moved. Thereafter, the biased locking screw locks the inner tube against the windage and elevation adjustment screws. In a modification of the preferred embodiment, the inner tube of the telescope may also be locked by using a locking screw constructed similarly to the elevation or windage screws in combination with a separate spring bias. The separate spring bias will apply a force against the windage and elevation screws of the telescope and the locking screw will lock the inner tube in place. The tube may also be locked by a third locking screw without using a bias.Type: GrantFiled: November 16, 1992Date of Patent: November 15, 1994Assignee: Burris CompanyInventor: John P. McCarty

Patent number: 5249080Abstract: A new coronagraph sufficiently increases the contrast ratio between the infrared image of a nonsolar star and a possible orbiting nonsolar planet to make imaging of such a planet possible. The coronagraph is used with an infrared telescope system having a square objective or aperture. Unwanted stellar irradiance is diffracted orthogonally by the square telescope aperture or objective so that a coronagraph apodizer in the first focal plane in the shape of crossed arms, and a coronagraph Lyot stop in the pupil plane with a square opening, stop most of the on-axis direct and diffracted stellar energy while allowing most of the planet irradiance to pass through the coronagraph. The discarded light reflected from the back of the apodizer can be used to provide information concerning piston and tilt errors of individual segments of a segmented telescope so that an array of correcting piston-tilt mirrors can be controlled to align the telescope.Type: GrantFiled: July 1, 1992Date of Patent: September 28, 1993Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Steven M.

Patent number: 5189560Abstract: Telescopes, both Galilean and astronomical, are mounted to small arms such as rifles, shotguns, pistols and bows. These telescopes are miniature in size mounted into the aiming mechanism of the small arm. The telescope imagery is engineered to produce simultaneous viewing of target and sight. Objects, including a barrel end post, at varying distances from the scope are all observed clearly, sharply and simultaneously on the image or exit pupil of the scope. This imagery may be enhanced with the use of glare control structures. Galilean scopes are herein described as being used with a reticle structure on the scope eyepiece or on, or beyond, the objective lens for calibrating/aiming guns and bows. The reticle figures are most accurately employed at eye relief distances of from near point (approximately 25 cm) to arms length (approximately 56 cm).Type: GrantFiled: February 15, 1991Date of Patent: February 23, 1993Assignee: Edwards Optical CorporationInventors: Bruce W.

Patent number: 5130845Abstract: A real image viewfinder with an objective having movable focusing lens(es) and a field lens at the end thereof furtherest from the field of view, an eyepiece lens and image inverting optics, preferably in the form of a Type II Porro prism wherein the real image is focused to fall on a surface of the field lens, which is desirably a plano surface facing the inverting optics. This field lens surface is also at the focus of the eye piece lens. A pattern (a reticle) is located on the field lens surface. Since the objective forms a focus at the location of the reticle, observation of the reticle indicates when the objective is focused. A camera picture taking lens may be coupled to a movable lens in the objective for focusing the taking lens.Type: GrantFiled: December 17, 1990Date of Patent: July 14, 1992Assignee: Eastman Kodak CompanyInventor: Paul L.

Patent number: 5107370Abstract: An astronomical data collection method employing a novel optical reticle projector. Prior art ground-based optical systems for astronomical data collection typically comprise a main telescope, and a guide telescope comprising an internal reticle. The guide telescope presumably corrects nominal tracking errors, but may itself, by way of the internal reticle, develop supererogatory errors due to differential flexure. The method of the present invention addresses the problem due to differential flexure, and solves it, by minimizing a source of the supererogatory errors, while recreating an internal reticle function in the novel optical reticle projector.Type: GrantFiled: January 17, 1991Date of Patent: April 21, 1992Assignee: Eastman Kodak CompanyInventor: Thomas W.

Patent number: 5052790Abstract: To provide for bi-level viewing through a miniature Galilean telemicroscope, the telemicroscope is mounted to a carrier such that its optic axis is angled relative to a principal optic axis defined by the carrier. The carrier may be a spectacle lens, an adaptor to be pressure fit to the rear portion of the aiming mechanism or a gun, or an adaptor to be coupled to an optical instrument. The miniature scope may also be used as the principal sight aperture. Where the optical instrument is a larger telescope, an additional cross hair allows for alignment of the telemicroscope. Fibers extending inwardly from the inner surface of the telemicroscope barrel minimize internal light reflection. The telemicroscope barrel is formed of threaded-like coupled portions which may be rotated relative to each other for focusing.Type: GrantFiled: September 1, 1989Date of Patent: October 1, 1991Assignee: Edwards Optical CorporationInventors: D.
