ABSTRACT:
A laser range finder, including a transmitter, a receiver, a timing-counting module, and a processor is provided. The transmitter transmits a laser signal toward a target, and a reflected signal is reflected from the target, whereby a real fly time is defined. The time-counting module generates a plurality of timing units to measures the real fly time to obtain a measured fly time. The processor generates a distance value based on the measured fly time.
