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.
