The Lidar Applications Group is based out of the Science Directorate at NASA’s Langley Research Center. The research campaigns and experiments performed in the Lidar group use Lidar technology on various aircraft to learn more about our atmosphere, what’s in it, and how it’s changing. brings you the latest images, videos and news from America's space agency. Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. The NASA Langley Research Center DAWN (Doppler Aerosol WiNd) lidar system employs a pulsed, solid-state laser operating at nm wavelength. It pulses at 10 Hz with up to mJ/pulse which are ns long. Using a wedge scanner, several different azimuth angles can be measured below the aircraft, all at a 30 degree off-nadir angle. LITE was a three-wavelength backscatter lidar developed by NASA Langley Research Center to fly on the Space Shuttle to support advancement of knowledge of Earth as a system to meet the chanllenges of environmental changes, and to improve life on our planet.

II. Flash Lidar Sensor Overview The principal of flash lidar sensor system is illustrated in Fig. 1. The Flash Lidar uses a two dimensional detector array. Compact, high-efficiency lidar instruments for deployment on unconventional platforms, such as balloon, small sat, and CubeSat are also considered and encouraged. Proposals must show relevance to the development of lidar instruments that can be used for NASA science-focused measurements or to support current technology programs. Because this type of lidar has never flown in space, the LITE mission is primarily a technology test. Scientists and engineers want to verify that the entire system works as planned in orbit, for example, that the laser and telescope remain aligned, that the built-in cooling system can handle the heat produced by a powerful lidar instrument and that the signals and noises are measured as expected.

Designed to operate at high altitudes in order to obtain measurements above the highest clouds, the instrument provides the true height of cloud boundaries and the density structure of less dense clouds. LIDAR is the optical analogue of RADAR (RAdio Detection And Ranging). The only thing that separates LIDAR from RADAR is the energy source. LIDAR’s source being a laser in the optical part of the electromagnetic spectrum. LIDARs are active remote sensors since they include the light source on which the measurement depends.
