Abstract:
A system for covert sensing. A broadband light source is split into two portions, a first portion of which illuminates a target, and a second portion of which is frequency shifted, e.g., by an acousto-optic frequency shifter. Light reflected from the target is combined with the frequency shifted light, detected, and demodulated with an in-phase and quadrature demodulator. The outputs of the demodulator are filtered and the arc tangent of the ratio is calculated.

Claim (Index 20):
The system of  claim 19 , wherein the combined optical delay and frequency shifter comprises an optical delay, wherein the optical delay is configured to provide an adjustable delay, the delay being adjustable in increments of 1 picosecond or less.
