摘要： A first volume hologram diffracts a portion of the beam of light as a first beam and transmits the remaining portion of the beam of light as a second beam. A second volume hologram diffracts either the first or the second beam to a desired angle and transmits the remaining beam undiffracted. Desired beam separations at desired angles may thereby be achieved for use in optical data storage systems.

摘要： A system is disclosed for preventing processing of duplicative coded label signals generated by a scanner lacking item detectors. The system establishes a variable lockout time as a function of operator performance. Any detected label candidate which duplicates a candidate received within the lockout time is assumed to be duplicative. Any transfer to the terminal is inhibited. Operator performance is tracked by measuring the inter-item arrival times for candidates actually transferred to the terminal. The inter-item arrival times are averaged over a given number of items. The average value is used to select a lockout time which is generally proportional to the average inter-item arrival time.

摘要： Production quantities of a multi-element holographic scanner disc are made by optically replicating a silver halide master disc one element at a time in a dichromated gelatin film. The dichromated gelatin film swells during processing. The swell is monitored during production by determining the shift in the angle of the Bragg surfaces within the gel. The angle of the replicating beam for each element is changed from that of the original reference beam to establish a Bragg angle at exposure which will be tilted to the proper angle after swelling in order to maximize the diffraction efficiency of the element at the original reference beam angle.

摘要： A hologram system comprises two volume holograms on two separate substrates which are cemented together with an optical cement. The two volume holograms are manufactured with identical Bragg planes. The two volume holograms are oriented with respect to one another such that the Bragg planes are optically aligned. The result is that the two volume holograms operate as a single thicker volume hologram wherein the Bragg angle sensitivity is greatly increased.

摘要： An optical scanner uses frequency modulation and detection techniques to produce and utilize multiple, simultaneous scan patterns in which corresponding scan lines have different focal lengths. Two or more solid state lasers are modulated at unique frequencies. The frequency modulated output beams pass through different combinations of focusing lenses and are deflected by a single beam deflecting apparatus. Light reflected from any scanned object is detected. The resulting multi-frequency signal is applied to a plurality of bandpass filters to separate the returned signal into a plurality of separately decodable signals.

摘要： A hologram system is comprised of two identical volume holograms. Both holograms have Bragg planes oriented perpendicular to the surface of the hologram. The first volume hologram separates a single beam into two orthogonal polarization component beams. The second volume hologram diffracts one of the polarization component beams such that a desired separation angle is achieved between the two beams. This separation angle may be precisely adjusted during manufacture by orienting the Bragg planes of the second volume hologram at a rotational angle with respect to the Bragg planes of the first volume hologram.

摘要： A hologram element receives a first and second laser beams at a first angle relative to one another. The hologram element emits the laser beams at a second angle relative to one another. The second angle is less than the first angle. The result is that laser beams from widely divergent laser sources may be directed into the same optical channel. Closely spaced beams are thereby provided for multiple beam optical data storage systems.

摘要： This disclosure describes a technique for reading bar codes scanned by focussed scan lines having different focal lengths where at least one of the scan lines has a beam that is small relative to irregularities of the surface on which the label appears. The scan lines are generated using a holographic disk so as to have a predetermined focal length and focal zone. The focal zone of each generated scan line overlaps the focal point of at least one adjacent scan line. Any bar code label which might be scanned by a beam so small that it would be degraded by surface scatter noise is also scanned by a slightly larger beam. The slightly larger beam "averages out" the surface scattering noise to produce a smoother or cleaner return signal.

摘要： A dual beam laser array provides two overlapping beams for use in a direct read after write (DRAW) optical data storage system. A first portion of the overlapping beams is directed to a first optical detector and a second portion of the overlapping beams is directed to a second optical detector. A logic circuit connected to the optical detectors generates power signals representative of the power levels of each of the overlapping beams without the need to completely separate the beams.
