Abstract
An object detection system to sense obstructions in the path of
low speed vehicles is described. The system uses a pulsed GaAs
diode laser as an illuminator, and a PIN photodiode as a detector.
Reliable detection of objects with an effective area as small as
2
0.5 ft was achieved. A signal processor using active filters and a
phase-locked loop tone decoder was employed for both phase and
frequency rejection of undesired signals, and detection of objects under
high ambient light conditions.
