Advanced Underwater Imaging Phase III Annual Report FY07
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-inch diameter and smaller form factor autonomous underwater vehicles (AUVs). The objectives of the work performed during this funding period were to: 1. Gain an understanding of the limitations of the simulation results obtained with the pulsed laser line scan (PLLS) time history and image simulation software, by comparing simulation results with measured data. 2. Gain an understanding of the technological and system performance trade-offs in the design of a wide-swath extended range underwater optical imager (ERUWOI) which is suitable to be deployed from the common form factor AUV. 3. Analyze the performance of candidate autonomous image quality optimization computer algorithms using measured data to provide a metric for comparison of the PLLS and LLS imaging methods. 4. Investigate the potential to achieve increased system range and image contrast via the use of high frequency pulse modulation and coding techniques.
