Chaotic LIDAR for Naval Applications
Abstract
A high power, wide bandwidth green optical transmitter has been developed which is suitable for experimental underwater LIDAR work. Previous reports have detailed the generation of 50 mW of 532 nm green light with wideband frequency content appropriate for high resolution ranging in water. This report details improvements to the laser design in efficiency and signal output and also presents our first experimental demonstration of chaotic behavior. Two preliminary proof-of-concept system experiments are also presented. The first shows rangefinding with centimeter accuracy using a digital receiver for unambiguous ranging at arbitrary distances. In the " second experiment, we use the laser signal to probe an unknown charmel and determine its frequency response. This technique for finding the instantaneous underwater channel response will be useful for determining best operating conditions for wideband transmitters.
