Advanced Underwater Imaging Phase IV Annual Report FY08

Abstract

The overall objective of the Advanced Underwater Imaging (AUI) program is to advance the state-of-the- art in wide-swath underwater laser imaging with the long-term goal of transitioning this technology to the Navy's fleet of 21" diameter and smaller form factor autonomous underwater vehicles (AUVs). Following the development and refinement of benchtop pulsed laser line scan (PLLS) imaging hardware and image simulation tools in FY07, the objectives of the work performed during this funding period were to: 1. Perform experimental validation of time history code for underwater PLLS model 2. Experimental comparison of CW/pulsed/ modulated-pulse variants of LLS 3. Analytic comparison between CW/pulsed/modulated-pulse variants of LLS 4. Application of image quality algorithms to acquired images 5. Complete experimental hardware to allow for wide-swath LLS imaging.
