Self-Detecting Optical Sensors.
Abstract
A short-ranging laser system having an improved pulser which includes a drive pulse signal generator and a driver. The drive pulse signal generator is essentially a triggered bipolar avalanche transistor that outputs a drive pulse signal through a voltage shifting circuit to the driver. The driver is essentially two parallel-connected power MOSFETs that output a driver pulse to a GaAs heterojunction laser diode. By circuit design, the deadtime plateau is substantially reduced so that the laser return energy homodynes with the still active laser to produce a detectable output for a target within 5 meters.
