Abstract
Recent research efforts on detector arrays in the near-infrared (NIR) and the short-wave infrared (SWIR) wavelength range have led to compact and robust 3D flash lidar architectures [1]. This technique can provide real-time 3D mapping of an area in various weather conditions for surveillance, but also for detection of moving objects in guidance of unmanned vehicles. Today main size limitation for compact, portable systems is the pulsed laser source. An alternative to solid-state or fiber lasers could be laser diodes since they have a better efficiency and their beam profile is compatible with active imaging by flash illumination. This paper will present recent advances in mJ class pulsed laser diodes made by Quantel Laser, France. Experimental results will be described both in NIR and in SWIR bands.
