We proposed to develop a high-resolution three-dimensional imaging LADAR system based on the principle of photon-counting and highly-resolution time-correlated measurements. Imaging capability of this photon-counting LADAR PC-LADAR was also proposed to be enhanced using polarimetric measurements. Following are some of our notable accomplishments 1. Components for developing the PC-LADAR system have been acquired. This includes purchasing of major components such as picosecond laser sources LDH-P-C-705 and LDH-P-C-840, PicoQuant, single photon detectors PD-100-CTC-FC, Micro Photon Devices and SPCM-AQRH-16, Pacer-usa, picosecond event-timer HydraHarp 400, PicoQuant, and high-bandwidth oscilloscope DSO-X-4054A, Keysight Technologies etc. 2. A software interface for PC-LADAR is developed for performing synchronized beam scanning with the laser transmitter. 3. Receiver assembly for PC-LADAR is designed using a large aperture eight inch telescope objective lens. Assembly design for the complete system is currently under progress. 4. Basic characterizations of the event-timer module for time-of-flight TOF measurements have been performed. 5. Experiments using a scanning LADAR prototype were conducted to demonstrate improvement in TOF or range resolution using a new multi-pulse detection scheme. 6. Students one graduate student and two undergraduate students are trained in performing LADAR system design, hardware testing and data acquisition.
