Note(s): Experimental results from two alternate approaches to underwater imaging based around the well known Laser Line Scan (LLS) serial imaging technique are presented. Traditionally employing Continuous Wave (CW) laser excitation, LLS is known to improve achievable distance and image contrast in scattering-dominant waters by reducing both the backscatter and forward scatter levels reaching the optical receiver. This study involved designing and building prototype benchtop CW-LLS and pulsed-gated LLS imagers to perform a series of experiments in the Harbor Branch Oceanographic Institute (HBOI) full-scale laser imaging tank, under controlled scattering conditions using known particle suspensions.
