摘要： A holographic method and apparatus for storing and retrieving information only by authorized persons, particularly used for identifying the bearer of a record of such information, comprises storing the information on a record medium as a hologram, scrambling the image of the information on the hologram so that it cannot be recreated except by authorized persons using a master code, and then recreating the scrambled holographic image using apparatus that eliminates the effect of the master code. The information is recreated and displayed using apparatus for displaying holograms which further includes a master code hologram that is reciprocated across the optical axis of the display apparatus so as to eliminate the scrambling effect of the master code on the hologram. The master code may consist of a series of parallel randomly undulating lines.

摘要： 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.

摘要： 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.

摘要： A laser-based rangefinding instrument for, inter alia, golfing or hunting activities having an unique ergonomic design and an external multi-function switch for controlling display brightness, selectable display of differing distance units and a slope selection switch for enabling display of line of sight distance or angle of slope and “Compensated Golf Distance” angle corrected distance to a target.

摘要： 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.

摘要： 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).
