Abstract

The realization of a portable laser rangefinder, capable to measure ranges up to 1,200 m, raises some difficult problems. The first one is that a good temporal resolution is required to get a good ranging resolution and that means that both the transmitter and the receiver must be rapid. The other problem is that at measurements of range larger than 1,000 m the level of the reflected pulse current in the phodiode is of the order of the dark current, which has to be compensated, as well as the temperature offset of the photodiode (in order to keep the calibration). A novel solution was adopted to solve these problems: the AC coupling (it doesn’t matter any more the dark current nor the temperature offset) and the use of wide band amplifiers, with a very low noise.
