An ongoing challenge for laser-based ultrasound sensors is to improve the sensitivity of adaptive photodetectors. This class of sensor is compact, robust, and simple to implement. Moreover, it can optically detect the desired ultrasound information a

The trend toward intelligent manufacturing has produced an increase in the need for sensors which can nondestructively evaluate components and processes in real-time. One commonly used nondestructive approach is ultrasonic inspection. The most common

We describe a Compensated Laser Ultrasonic Evaluation (CLUE™) system which combines a wavefront scrubbed laser receiver with a pulsed laser ultrasonic generator. The receiver uses nonlinear optics to compensate for the speckle produced by the surfa

It is well known that phase-conjugated light has an ability to correct the phase distortion introduced while passing through a phase distorting medium.

Optical processing devices based on a phase conjugate resonator have high spatial resolution, resulting from the large number of transverse modes that are allowed. However, these devices are also subject to spatial and temporal instabilities due to t

We report on the demonstration of an all-optical, closed-loop adaptive optical compensation system and white-light compensated imaging scheme using a liquid crystal light valve (LCLV) as the correction element. A typical LCLV is a two-port device con
