Abstract:
An optical distance measuring system includes a transmitter and a receiver. The transmitter is configured to generate a first optical waveform and direct the first optical waveform toward a first scan point within a field of view (FOV). The receiver is configured to receive the first optical waveform reflected off a first object within the FOV, direct the first optical waveform reflected off the first object to a first photodiode group of an array of photodiode elements, and determine a distance to the first object based on a time of flight of the first optical waveform from the transmitter to the first object and back to the receiver.
