DEFINITION

Classification: 356/3.14

Using at least a pair of viewing axes:

(under subclass 3.13) Subject matter which includes two optical axes relating to the target directed to at least two photodetectors or detector arrays in the generation of a pair of electrical signals related to the triangle that defines the distance to the target.

(1) Note. The detector(s) may be mono- or multi-element, and further scanned or staring.

(2) Note. This subclass includes passive image correlation of two images from a single target source in establishing two angles to the target.

SEE OR SEARCH THIS CLASS, SUBCLASS:

3.08, for a pair of staring mono- or multi-element detectors used where a single source maintains a fixed axial direction.

3.15, for image correlation where a photodetector views images of a target and where one of the images is established along a fixed line of sight.

4.04, for split-image separation detection of "focus" quality where there is no baseline separation between the separate image viewing axes as here in subclass 3.14. SEE OR SEARCH CLASS

348, Television,

139, for triangulation of range derived from two or more picture images generated and compared based on their baseline separation.
