Architecture for low-cost laser range finder system

摘要

A laser range finder including a receiver (16) for detecting a return pulse and providing an output signal indicative thereof, a single integrated circuit digital range counter chip (25) connected to receive the output signal from the receiver (16), a power supply unit (17) for powering the receiver (16) and range counter chip (25), and a single-chip microcontroller (13) for selectively sequencing application of power to the receiver (16) and to the range counter chip (25), for controlling laser firing, and for automatically recalibrating the receiver (16).
