Paper Abstract

An inexpensive aerosol lidar is proposped by combining inexpensive fiber-coupled diode laser and photon counting detection technology for air quality monitoring in metropolitan area. A prototype lidar system was built with a 100 μm fiber-coupled diode laser as the laser source and a 200 mm Schmidt-Cassegrain telescope as the receiver. The transmitted beam diveregence from a 50 mm diameter Galilean transmitter was 433 μradian and the receiver field of view was 133 μradian in full angle. With a repetition rate of 5 kHz of 100 ns pulse, a signal-to-noise of 2 was obtained up to 2 km in a clear day nighttime at the averaging time of 60 s.
