Eye safe laser rangefinder for transport safety

We develop an ultracompact and lightweight eyesafe laser rangefinder for distances up to 10 km. It uses 1 mJ Yb:Er:glass diode pumped passively Q-switched laser and InGaAs avalanche photodiode with time dependent gain management. It gives 0,5 m RMS accuracy at distances up to 5 km and 1 m RMS accuracy up to 8 km. The design is robust and vehicle capable. The dimensions are 90x60x40 mm, weight is 200 g. Repetition rate is up to 5 Hz. The device gives pulsed laser rangefinder performance in half-palm dimensions and robust design.
