Abstract

Synchronous demodulation was applied to the Laser Optical Line of Sight system (LOLOS) used to measure deflections of a canister used in underground testing. The purpose of this was to achieve greater sensitivity and resolution than that found in the original system. Electronics and optical equipment were built or acquired to evaluate the concept. Under laboratory conditions sensitivity to lateral and angular displacements were improved by more than an order of magnitude.
