DUSTER is a monostatic biaxial lidar system. Emitter consists of a 20Hz Nd:YAG laser (Brilliant da Quantel SA). Receiving system uses a Cassengrain telescope with primary mirror diameter of 35 cm. Light is split to 4 detection channels: 1064 nm, 532 nm (parallel), 532 nm (perpendicular) and 355 nm, all read by LICEL hardware. Vertical resolution is 7.5m.
