Abstract: A compact beam scanning information readout device and method for reading bar code or other information requires little or no orientation of the information to be scanned by virtue of its raster or omni directional scan capabilities. Only a single mirror is needed to generate two dimensional scans. A wide range of scan speeds are also possible for simple or complex one or two dimensional patterns. Scanning in two dimensions may be done with independent and continuous control of the scan in each dimension. The scan patterns may be electronically controlled to instantly achieve various orientations ranging from a straight line rotated about a point to continuously rotating complex patterns. A light collector, light detector, processor, and means of signal transmission are also included. In one embodiment the device is packaged in a housing resembling a wand or a thin flashlight and in another embodiment the device is packaged in a ceiling mountable housing which will not interfere with counter top work space.

Abstract: A compact high efficiency electro-optical information collection system is ideally suited for application as an optical front-end receiver in miniature bar code reading systems, optical local area networks (LANs) used in computer communications and other such equipment. The invention includes a single component high efficiency photoelectric converter with nonimaging light collection element, integral filter, photo diode, and mounting means all combined in a miniature rugged package.
