3.09
.~.~ Requiring scanning of a source beam
DEFINITION
Classification: 356/3.09
Requiring scanning of a source beam:
(under subclass 3.01) Subject matter wherein the source comprises a beam of light that is moved at some angular rate that can be detected and associated with any one target's angular position.
(1) Note. The target may be at the source position or reflected by the source, but scanning is required to generate the angular information.
SEE OR SEARCH THIS CLASS, SUBCLASS:
3.02, for moved but not necessarily spatially scanned sources that define a target with respect to a fixed axial line of sight of a photodetector.
