摘要： An arrangement for reading bar code symbols including a laser diode unit having a forwardly-directed laser beam emitted along an optical path toward a symbol for reflection therefrom to generate reflected light, and a rearwardly-directed laser beam, and a monitor photodiode in optical communication with the rearwardly-directed laser beam for producing a signal indicative of the output power of the laser diode. The arrangement also includes a collector exterior to the laser diode unit for collecting at least a portion of the reflected light from the symbol, and for directing the collected portion to the monitor photodiode to generate an information signal descriptive of the symbol.

摘要： An electro-optical reader reads indicia having parts of different light reflectivity within a limited working range of distances relative to the reader. The reader includes a laser for emitting a laser beam, a photosensor for detecting light over a field of view and generating an analog signal indicative of the indicium being read, and a scanning motor for scanning the laser beam and/or the field of view. A digitizer for digitizing the analog signal, a laser drive for energizing the laser, and a motor drive for activating the motor are all mounted on a single chip integrated circuit mounted within the reader.
