Abstract
A digital counting and display system and methods for use with a laser rangefinder that counts backscattered laser beams and displays a distance between a laser and a target. The laser rangefinder includes a laser configured to emit a pulsed laser beam, an afocal Gallilean telescope configured to receive backscattered laser pulses and generate a series of focused backscattered laser pulses, a silicon avalanche photodetector connected to the afocal Gallilean telescope, configured to generate a series of currents signal proportional to the series of focused backscattered laser pulses, a low noise, multistage amplifier connected to the silicon avalanche photodetector, configured to generate a series of linearly changing amplified voltage signals from the series of current signals, an analog-to-digital converter configured to convert the series of linearly changing amplified voltage signals to a series of digital voltage signals, and a digital counting and display circuit connected to the analog-digital converter.
