Abstract

The “flash” ladar is a focal plane array (FPA) imaging system, which can supply the 3D-range and 1D-intensity imaging with high quality and frame rate. The high-speed flying platform needs a low-power-consumption and miniature ladar system. To meet this requirement, we proposed a “flash” ladar using an alexandrite laser without cooling system and an APD as a receiver, which can be miniaturized and working normally for a short time under the temperature field (60–80 ℃) of fast flying platform. Through the testing, a maximum detection range of 6 km, a spatial resolution of 1 degrees and a range resolution of 2 cm have been obtained.
