Planar beam-steering apertures for laser-transmitter applications require a true-time-delay (TTD) subsystem for enhanced data-rate performance. The requirements for such a subsystem depend on the overall aperture size, field-of-view, beam-steering sw

Beyond traditional communication needs, coherent detection systems are finding new applications in the areas of industrial inspection, phase-locking of free-running lasers, and spectral analysis. An example of the former includes laser-based ultrasou

In this presentation, we provide an overview of how real-time holographic processing in nonlinear photorefractive media, such as multiple quantum wells, can extract the coherent component of the scattered beam, resulting in the ability to image into
