Abstract
A scanned, one-dimensional, phased-array display system combines imaging optics on one axis with Fourier transform optics on another. The display offers the energy efficiency and fault tolerance of phase modulator-based displays, and the compactness, flexibility and speed of optical MEMS. Also described is a mechanism to introduce amplitude variations on the Fourier axis if needed to compensate for image artifacts.
