Beschreibung
Zusammenfassung:	The invention discloses a vehicle laser radar device for measuring pollution based on Raman light source. The device comprises a laser (1) and frequency converting components on the light path, a transmitting-receiving component and a control processing component electrically connected with the transmitting-receiving component. Wherein 1. the frequency converting components set on a automatic moving table (3) in sequence are two frequency doubling crystals with different multiple, collective convex lens (22), a Raman pipe group (6) with three parallel Raman tubes filled with different gas, a concave lens (23) and an alignment convex lens (24); 2. the transmitting-receiving component includes a transmitter and a receiver; 3. the control processing component is a microcomputer (52) which is connected with the pumping source of the laser (1), the input terminals of the stepper motor (19, 14, 33, 43), and the multiplier phototube (47) via I/O interfaces.
