l   InGaAs Photo Detector

l   Light Scattering

The pulsed laser module sends short pulses to an object of interest. Anoptical trigger signal starts the measurement and synchronizes one channel ofan oscilloscope (optionally available). The time of flight of the backscattered laser pulses determine the distance of the measured object. The pulsetemporal width reaches below 5 ns and distances of less than 40 cm can still bemeasured in the laboratory environment. Low laser beam divergence allows themeasurement of targets in distances of several tens of meters, still with astandard InGaAs detector. With a known target distance the kit can be used fordemonstration and measurement of the velocity of light. Since the laser moduleemits at 1535 nm, the laser radiation lays in the eye safe wavelength range.
