Binary optics: An emerging diffractive optics technology

The ultimate promises of emerging binary optics technology include sheet optics by the square meter, high-quality throwaway optical sensors, and arrays of hundreds of small modular lasers coherently added to form powerful laser beams. Binary optics refers to the two-level (high-low) nature of the phase-relief pattern used to control the phase, amplitude, and polarization of an optical wavefront.
