Abstract
Apparatus and method for using one laser range finder to calibrate another imilar range finder. The range finder under test receives a simulated return pulse from the transmitter of the second range finder. An external trigger initiates the transmitter of the range finder under test and a short time later initiates the transmitter of the second range finder. The transmitted beam of the second range finder is directed into the receiver of the range finder under test and it halts the range readout thereof. This range readout is compared to the reading on an external timer arranged to measure the time interval between the emission of the transmitted beams of the two range finders.
