DEFINITION

Classification: 356/3.04

With a single staring photodetector having one element:

(under subclass 3.03) Subject matter wherein a detector

produces an electrical signal related to the angular position of the source based on the instantaneous output of or differential output across a single detecting element that is not subdivided for its operation.

(1) Note. A one-element photodetector may consist of a lateral effect or photoresistive element.

3.03, for vidicon-type detection.

3.06+, for use of detectors that define the position of incidence of received light by the difference in the outputs of more than two detector elements (e.g., at least three separate photodetectors).
