A Compact Active Imaging System for Degraded Underwater Visual Environment

This novel technology consists of a sequence of coded illumination patterns generated via a digital micromirror device (DMD) coupled with a continuous wave (CW) laser to light up the target. A high dynamic range (HDR) commercially available camera records the sequence of images of the spatially, light modulated target. Thus, the novel technique helps...

LiDAR System and Inversion Algorithm for Turbid Environments

This technology is a novel underwater light detection and ranging (LiDAR) system with several transmitters that can be tuned for specific wavelengths along with several receivers that measure both fine spatial and temporal resolution of the light received. It includes an algorithm that inverts and corrects the recorded two-dimensional arrays of backscatter...
