Abstract
Liquid-crystal televisions are inexpensive display devices that can be used as arbitrary quasi-phase modulators to achieve arbitrary wavefront shapes, these are limited only by the available modulation depth and resolution. We discuss the properties of these devices and then demonstrate four applications of a particular liquid-crystal television: an active lens system, programmable optical image processing experiments, the resolution enhancement of an image sensor, and the measurement of the sensitivity of heterodyne detection to wavefront aberrations.
