摘要：
We have demonstrated a proof-of-concept optical device that can produce true time delays for a phased-array radar. This device combines White cells of differing lengths with a spatial light modulator to select between the paths on multiple bounces of a given beam. The approach can handle thousands of light beams and produce hundreds of different delays. The number of delays is proportional to the square of the number of bounces.
