    摘要： An integrated scanner/radio includes a bar code reader and an RF transceiver integrated on a semiconductor substrate. The bar code reader includes a light source, a scanner for directing light from the light source across a bar code symbol, and a detector for detecting the light reflected from the bar code symbol and creating an electrical signal representative of the detected light. The RF transceiver includes an antenna for transmitting and receiving modulated RF carrier signals.

    摘要： An integrated scanner for scanning a barcode is formed on a common substrate. The scanner may include a micro-machined mirror, a laser diode, and a detector, mounted on a single substrate or several connected substrates. Lenses can be used to focus a laser beam from the laser diode as well as expand a laser beam deflected by the micro-machined mirror. The scanner may also scan a barcode without using a micro-machined mirror by rotating the laser diode.

    摘要： An optical scanner includes a light source for producing a light beam for scanning a target wherein the light beam scans a target at a first low frequency and the beam also dithers in a direction orthogonal to the scanning direction at a second, high frequency. The dithering motion can be imparted by a oscillating mirror and allows improved reading of, for example, bar code symbols. In addition an optical scanner includes a laser light source producing a laser light beam into which a time-varying phase is introduced in order to reduce laser speckle noise.

    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 PIN GaAlAs diode structure is provided with parameters for index guiding of light in a single mode. The index of refraction of the central layer I (which in practice may be lightly doped .pi. or .nu.) is greater than the p- and n-layers to create a slab waveguide in the transverse direction. Stripe contacts define separate waveguide channels that are separated electrically and optically by implanting protons or etching grooves between the stripe contacts in the upper layer. Separate reverse biasing voltages may be applied to the stripe contacts for modulation of the light in proportions to the voltage, either with absorption modulation, if the light wavelength is within about 500.ANG. of the bandgap of the .pi.-material, or phase-delay modulation, if the wavelength is separated from the bandgap of the .pi.-material by at least 900.ANG..

    摘要翻译： PIN GaAlAs二极管结构具有用于在单个模式中的光的索引引导的参数。 中心层I的折射率（实际上可能是轻掺杂的pI或nu）大于p层和n层，以在横向上产生平板波导。 条纹触点限定了通过在上层中的条状接触之间注入质子或蚀刻凹槽而电和光学分离的分离的波导通道。 如果光波长在pi材料的带隙的约500安培范围内，或者通过吸收调制，则分离的反向偏压电压可以施加到带状触点，以与电压成比例地调制光，或者相位延迟调制 如果波长与pi材料的带隙分离至少900安培。
