Abstract
An imaging system () has a fixed lens combination (), a spatial light modulator (SLM) () and a linear detector array (). A scene image is scanned across a simple array () in a direction perpendicular to the array () by the SLM (). This is achieved by displaying a diffraction pattern on the SLM that changes to achieve the scanning. The diffraction pattern displayed typically has a linear element () and a quadratic element (42). By having a programmably changed combined chirp pattern () displayed on the SLM, and by being able to change it thousands of times a second, an army with fast read out can take the place of a 2-D imaging array.
