Abstract
The charge of pixels in a FPA array is retrieved by propagating an optical wave through a waveguide to interact with pixel charges from the FPA. An optical detector receives an optical wave altered by the respective pixel charges as it travels. The optical wave is sensed after passing through the waveguide. In a preferred embodiment, separate waveguides interact separate optical waves with charge from FPA pixels. Information concerning the charge is obtained with separate optical waves in the separate waveguides. In a preferred example of an N×M array according to an embodiment of the invention, a complete frame of data includes only N+M data values. A direct memory is also provided, where the pixel charges are held by maintaining an electric field to the pixels making the charge retrievable by an optical wave multiple times until the electric field is removed or reduced.
