DEFINITION

Classification: 356/3.03

Using a source beam with a fixed axial direction or plane:

(under subclass 3.01) Subject matter that includes a beam or plane of light from the target that has a fixed angular orientation with respect to a baseline to establish an angle of the triangle.

(1) Note. The use of a photodetector is not required for this subclass, but the use of a vidicon-type detector is found here.
