The aim of this experimental pulsed laser range finder is to demonstratethe properties of LIDAR (Light Detection and Ranging). Short and intensivepulses are sent to a corner cube reflector. A trigger signal generated byreference pulses starts the measurement. An optical diode guides the backscattered laser pulses towards the signal detector. The time of flightdetermines the distance of the measured object. The pulse width reaches lessthan 5 ns and distances of less than 40 cm can still be measured in thelaboratory environment. High peak power and low beam divergence allow distancemeasurements of more than 100 m, still with a standard InGaAs detector. With aknown target distance the kit can be used for demonstration and measurement ofthe velocity of light.
