Optical phased array technology has the potential to dramatically reduce the cost of pointing, tracking, beam stabilization, focusing, and beam fanouts. Optical phased array technology will also be able to provide an adaptive technology that allows internal optical system design 'reprogramming' as well as the traditional beam clean up functions. Flexible optical systems that can be reprogrammed will allow easier upgrade to include new technology or new requirements, a critical need for long life aircraft in a rapidly progressing and changing world. The vision for a final aperture is a simple flat surface similar to a flat panel display that provides random access rapid beam steering and other beam deflection functions. The vision for intermediate optical elements is one of reprogrammability to adapt to future requirements and technology developments. Three major approaches are considered to provide the physical implementation of optical phased array capability. They are liquid crystal writable grating technology, deformable micro- mirrors, and lenslet arrays.
