Class Information
Number: 250/203.2
Name: Radiant energy > Photocells; circuits and apparatus > Photocell controls its own optical systems > Following a target (e.g., a star or instrument pointer or other object) other than a pattern > Target illuminated by artificial light source
Description: Subject matter in which the object to be tracked is, as disclosed, illuminated by an artificial light source, e.g., a laser, and the light from that source which is reflected from the target is detected and used to track the object.
