The LEE capable of emulating the echoes of a spatial lidar at three wavelengths (355 nm, 532 nm, and 1064 nm) was developed. In general, it enables the characterization of the critical optical parameters of the detection chain of a space or airborne lidar. The LEE allows short overlapping echo with long echo with 63 dB dynamic range. In-depth characterization of the lidar detection module will evaluate compliance with the requirements for which it was designed and feed future designs with actual figures from the lidar detection chain.

The LIDAR Echo Emulator (LEE) emulates the returned signals from a Lidar system. As the return signal of a Lidar system depends on the target, this implies the capability of shaping the laser’s returns. In brief, a long echo corresponds to a natural or diffusive object (canopy, clouds) and short echoes to a complex thing like roofs, ground, etc. Such signals must be simulated to study and validate new detectors and detection systems without developing/procuring the entire Lidar system.

High brightness semiconductor lasers are potential transmitters for future space lidar systems. In the framework of the European Project BRITESPACE, we propose an all semiconductor laser source for an Integrated Path Differential Absorption lidar system for column-averaged measurements of atmospheric CO2 in future satellite missions.
