An imaging system ( 10 ) has a fixed lens combination ( 22 ), a spatial light modulator (SLM) ( 20 ) and a linear detector array ( 12 ). A scene image is scanned across a simple array ( 12 ) in a direction perpendicular to the array ( 12 ) by the SLM ( 20 ). This is achieved by displaying a diffract...

Beschreibung
Zusammenfassung:	An imaging system ( 10 ) has a fixed lens combination ( 22 ), a spatial light modulator (SLM) ( 20 ) and a linear detector array ( 12 ). A scene image is scanned across a simple array ( 12 ) in a direction perpendicular to the array ( 12 ) by the SLM ( 20 ). 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 ( 40 ) and a quadratic element (42). By having a programmably changed combined chirp pattern ( 36 ) 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.
