HARBOR BRANCH OCEANOGRAPHIC INST INC FORT PIERCE FL
Pagination or Media Count:
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 Navys 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 CWpulsed modulated-pulse variants of LLS 3. Analytic comparison between CWpulsedmodulated-pulse variants of LLS 4. Application of image quality algorithms to acquired images 5. Complete experimental hardware to allow for wide-swath LLS imaging.
