Paper Abstract

This paper describes a versatile, low cost laser range finder, which uses a GaA1As laser diode transmitter operating in the near infra-red region at a wavelength of 820nm. A silicon PIN diode receiver captures the reflected laser pulse from the target and a high speed counter measures the time of flight of the laser pulse. A microprocessor based circuit is employed for automatic calculation and visual display of range distance.
