  • Patent number: 10969689
    Abstract: The present invention discloses an apparatus for making direct writing screen plate and a using method thereof. The present invention provides a direct writing screen plate making apparatus and a focal plane control method. A Z-axis controller is used to pre-establish a mapping relation between the focal plane position of the scanning band to be scanned in the next step and the scanning platform position signal. During the next step of scanning, the position of the optical lens is adjusted according to the mapping relation, thus avoiding the problem of inconsistency between the calculated focal plane and the actual focal plane caused by the position deviation between the assembled displacement sensor and the optical lens. The present invention also provides a method for exposing a region of interest and a method for compensating the on-line real-time light uniformity.

  • Patent number: 10942275
    Abstract: A method and apparatus for improving measurements of a laser beam in a laser imaging system. The method includes, positioning an apodizing filter having a transmission profile that approaches a maximum at its edges between a pixelated detector and a laser source. The method further includes, emitting a laser beam from the laser source onto the apodizing filter and transmitting a portion of the laser incident upon the apodizing filter to the pixelated detector in accordance with the transmission profile of the apodizing filter such that the signal-to-noise ratio of the portion of the laser incident upon the pixelated detector is improved. The apodizing filter may be selected from a linear apodizing filter, a radial apodizing filter and a prism apodizing filter.

  • Patent number: 10708537
    Abstract: A method and apparatus for reducing ghost images in a laser imaging system. The method includes, positioning an absorptive neutral density filter, having an optical density (OD) of at least ?1, between a pixelated detector and a laser source. The method further includes, emitting a laser beam, from the laser source onto the absorptive neutral density filter, transmitting a portion of the light incident upon a first surface of the absorptive neutral density filter to a second surface of the absorptive neutral density filter, reflecting a portion of light incident upon the second surface of the absorptive neutral density filter and absorbing the reflected portion of light, by the absorptive neutral density filter, to reduce ghost images at the pixelated detector.

  • Publication number: 20200160700
    Abstract: Disclosed herein is a handheld speed gun incorporating automatic number plate recognition (ANPR) functionality. As the image size of a vehicle license plate varies depending on its distance from the speed gun, in the present invention the distance to the target vehicle is known through the functionality of the laser sensor so the size of the pixels for the number plate can be estimated. Since the image of the number plate may be tilted in a handheld device, the present invention compensates for this by use of the instrument's tilt sensor or through other compensation by use of the image itself.

  • Patent number: 10545457
    Abstract: In an embodiment, an off-axis hologram is provided. The off-axis hologram creates two, conjugate images which are on either side (off-axis) of the 0-order beam. A Multiple Beam Grating (MBG) is used to both duplicate the conjugate images and to redirect the images along the axis. The 0-order beam is blocked before or at the MBG. The MBG projects the images onto a 3D surface, such as a person's face.

  • Patent number: 10509128
    Abstract: In an embodiment, an optical projector is provided with a laser array. Each laser is either collimated or focused to a fixed distance. At least one multiple beam grating (MBG) is placed in front of the laser array. The light pattern from the laser array is duplicated by the MBG, and cast on an object to be measured. The pattern on the object is changed by rotating the MBG. As a result, the number of patterns of structured dots that can be projected on the object is nearly unlimited. The optical projector can be used to provide depth perception to motion detection systems, to vehicle self-driving systems, and for many other uses.

  • Patent number: 10317684
    Abstract: In one embodiment, the light from a single laser is used to illuminate a pattern-generating optical element to generate a pattern. The pattern-generating optical element in various embodiments can be, for example, a holographic diffractive optical element (DOE) or an array of micro-lenses. A multiple beam grating (MBG) duplicates the pattern multiple times to provide a multiple pattern image. A lens is used to project the patterns onto an object. In one embodiment, the lens is located between the pattern-generating optical element and the multiple beam grating (MBG).

  • Patent number: 10145940
    Abstract: A system and method for a rangefinding instrument incorporating pulse and continuous wave signal generating and processing techniques for increased distance measurement accuracy. The use of the former technique effectively solves the ambiguity issues inherent in the latter while allowing for relatively simple circuit implementations. Thus, a potentially more accurate phase-based distance measurement technique can be utilized which is also completely independent of the maximum range to the target.
