摘要： A colorimeter capable of calibrating color monitors, whether having cathode ray tube or liquid crystal (LCD) displays, is provided by a photometric array of photodetector and optical filter pairs. The filters include long-pass, edge filters which cover overlapping regions at the upper end of the visible spectrum and a filter which covers the entire visible spectrum. The outputs of the photodetectors are digitally synthesized to provide a response which mimics the response established by the Commission Internationale de l'Eclairage (CIE) xyz (bar) functions almost perfectly. The response which is mimicked may be represented by the CIE color matching functions. The pairs and the associated components are mounted on a printed circuit board captured in a clamshell housing and having an array of apertures which define angularly constrained fields of view of a surface from which the light, to be colormetrically analyzed, emanates. The colorimeter is capable generally of measuring the color characteristics, especially the color temperatures of radiation radiating and reflecting bodies (sources), including so-called black bodies.

摘要： An improved bar code scanning and reading apparatus which is adapted to be hand-held utilizes anamorphic optics for scanning and reading the code by providing a beam having an oblong cross-section in the nominal plane of the code. The oblong cross-section may be aligned with the bars of the code. The optics does not focus the beam in the longitudinal direction of the cross-section at the nominal plane of the code so that diffraction effects which would otherwise cause rotation of the cross-section of the beam to a position transverse to the bars of the code which would preclude reading of narrow bars, is avoided. The last lens of the anamorphic system may be a cylindrical lens which provides a line focus of a visible marker beam while at the same time providing the oblong cross-section of the beam which scans the code. The light from the vicinity of the code passes through the cylindrical lens and is collected by a toric reflector which projects the incoming light onto a photodetector. Power for operating the source of the scanning beam (a laser diode) is conserved by an opto-electronic system responsive to the movement of the sectors of a rotating beam deflector (a polygon reflector) so as to enable power to be applied to the laser only during the intervals when the beam is disposed within the limits of its scan path.

摘要： In order to meet the requirements for laser radiation safety, namely laser output which can enter the naked human eye indefinitely and cause no discernible damage (Class I emission limit) in a code symbol (bar code) scanner, a mode controller is used for generating a laser enabling the signal so as to turn the laser on in a search mode until the symbols are acquired and in an in-code mode while the symbols are being scanned. When the laser is turned on it operates at a power output which would exceed the Class I emission limits if operated continuously. Circuitry is provided for operating the mode controller so that the laser is not enabled to turn on for a period long enough to exceed Class I limits. Such circuitry may be an integrator or accumulator which responds to the time that the mode controller turns the laser on and which provides an output for inhibiting the mode controller from turning the laser on for a period of time sufficient to prevent the Class I emission limit from being exceeded. The circuitry may alternatively be a pulse generator which permits the mode controller to turn the laser on repetetively during a "find paper" mode with a duty cycle such that the Class I emission limits are not exceeded.

摘要： An optical device for detecting bar codes (markings or patterns which symbolize data such as the name and vendor of a product) are detected by an optical device which serves as a bar code scanner. A laser diode and associated optics provides an invisible beam. A visible marker beam coincident with the laser beam is generated by a lamp and associated optics and directed coaxial with the laser beam so as to enable the laser beam to be scanned across the bar code by moving a housing in which the laser and the lamp and their associated optics are disposed. Also contained in the housing is a photodetector on which scattered light from the code is incident after passing through a collection lens located at an outlet port for the beams. An aperture is positioned between the collection lens and the detector. The location and size of the aperture and the focal length of the lens are related such that the illumination by the reflected light of the detector is substantially constant and the output signal from the detector which represents the bar code is also constant amplitude over a wide depth of focus in front of the beam port. Unwanted reflections (gloss over the bar code) are rejected by selecting the polarization of the reflections opposite to the polarization of the laser beam, as by the use of a polarizing beam splitter. A spectral beam splitter is used near the detector to select the scattered laser light for the photodetector which generates electrical signals corresponding to the bar code.
