Abstract
An imaging or sensor system comprises a transmitter assembly, a receiver assembly and a control unit. The transmitter assembly defines an outgoing optical beam transmission path with respect to a target surface and the receiver assembly defines a return optical signal transmission path from the target surface. Each of the paths includes transmission through or reflection from at least one microdisplay device comprising a plurality of controllable elements for selective placement in a transmit mode for transmission of light along the transmission paths. A control unit selectively places the microdisplay device elements in the transmission mode.
