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.
Claims58
An optical scanning system comprising:
- a light source;
- a scan element for scanning a light beam from said light source;
- an optical element coupled to said scan element for receiving light from said light source and directing light toward a target;
- a nonimaging light collector for receiving and concentrating reflected light from said target;
- and
- a photoelectric converter for receiving concentrated light from said nonimaging light collector and producing electrical signals which are responsive to said received light.
An optical transceiver system comprising:
- a light source for transmitting light signals in the direction of a target;
- a modulation means for modulating said light source;
- a nonimaging light collector for receiving and concentrating light received from a target;
- and
- a photoelectric converter for receiving concentrated light from said nonimaging light collector and producing electrical signals which are responsive to received light.
An electro-optic component for collecting and concentrating optical information signals and converting said optical information signals into electrical signals comprising:
- a nonimaging light collector;
- a wavelength-selective optical signal filter;
- a photoelectric converter proximate said nonimaging light collector for converting said optical information signals into electrical signals and a housing for mounting and containing said nonimaging light collector and said photoelectric converter together as a single component.
