摘要
The range finding appts. can be carried on vehicles including track vehicles in e.g. mines. It protects against possible collisions. The sender has a l.e.d. and a focussing optical system to transmit a focussed, intensity modulated infra-red beam. A receiver, coaxial with the light beam, has a photodiode for reception of a reflected part of the i.r. beam. An evaluating device following the receiver responds to the reflected light phase and generates a signal corresponding to the distance to the reflecting object. The focussing device is a parabolic reflector with the l.e.d. at its focus. It is concentrical with the receiver.
