Flash imaging sensors for space applications

This paper presents the evaluation of two perspective techniques in flash imaging lidar realization for space applications. One of these techniques is the indirect time-of-flight measurement, implemented in the combination of APS/IPPD array and continuous wave harmonically modulated laser. The other technique is the direct time-of-flight, realized in a combination of SPAD array and picosecond pulse laser. A prototype and a breadboard are realized and tested, respectively for the both flash imaging lidar techniques. The test results allow conclusions for the perspective area of applications in future space missions of each of these techniques.
