Abstract
Techniques are disclosed that provide a multi-mode sensor having the capability to support both passive and active operation. One embodiment provides a sensor readout device for operation with a sensor array having rows and columns of detectors. The device includes a column cell for receiving a detector output signal from a first row of a column of the sensor array, and an additional column cell. The device further includes a multiplexer configured to steer a detector output signal from a second row of the column of the sensor array to the additional column cell, thereby allowing multiple rows of the sensor array to be readout simultaneously. In some cases, the sensor array includes an active/passive dual mode central windowed area, and the multiplexer allows columns of the windowed area to be readout at two or more speeds.
