    摘要： Several embodiments are disclosed of bar code readers in which one or more piezoelectric bimorph elements are utilized as a drive element in the optical system thereof. In different embodiments, the piezoelectric bimorph element is utilized in the scanning function of the bar code reader optical system, or in a variable focus zooming function of the optical system. The bar code readers are provided with improved decoding reliability, speed and orientation freedom, with regular or high density, one or two dimensional bar codes, by using multiple beam symbol crossings, created by using one or more piezoelectric bimorph elements. In different disclosed embodiments, one or more cantilever mounted piezoelectric bimorph elements support a scanning mirror, or a focusing lens, or a laser diode, or a laser diode and limiting aperture, for movement at the free ends of the bimorph elements to produce a scanning of the bar code reader optical system. Several disclosed embodiments of the subject invention provide a beam deflector for a bar code reader optical system having a variable focus zoom lens system in which one or more cantilever mounted piezoelectric bimorph elements control the variable focus zoom lens system. 1

    摘要： A hand-mountable adaptive bar code scanner includes a scanner for generating a light beam directed toward a target, the light beam sweeping the symbol to be read. The scanner further includes a photodetector for receiving reflected light from such symbol, and circuitry to determine whether the signal received is sufficiently distinct to determine that a valid symbol has been scanned, and signal processing circuitry having adjustable gain, bandwidth, and digitizer threshold characteristics for processing such signals.

    摘要： In order to improve security for holographic labels which are positioned on a substrate base, a bar code symbol with regions of different light reflective properties is holographically recorded on the base. The base may be, for example an information card, such as a credit card, a label, or a container for a product. The bar code symbol can be recorded so that it is visible to the eye in white light (e.g., as a rainbow hologram) or so that it requires an appropriate reference beam for reconstruction. A reading apparatus (e.g., a bar code reader) directs light at the holographic bar code symbol and detects the reflected optical information with a detector such as a CCD array. The reading apparatus can be a stand-alone device or, in the case of a credit card, can be incorporated into a conventional swiper for reading magnetic information on a strip on the card. A non-holographic bar code symbol can also be provided on or near a holographic display element, e.g., a rainbow hologram. The bar code can be positioned adjacent the display, or placed in a window within the display, or etched or embossed on the display. A system is also provided for authenticating a holographic display on an information card such as a credit card. A display is illuminated and a reflected beam directed at a holographic record which was previously produced from a signal, known to be authentic, and a reference. The reflected beam is used to reconstruct a reference beam. A sensor receives the reconstructed reference and it is then determined if the display is authentic.
