Abstract
Digital data processing unit includes two SLMs assembled back-to-back with a common photoreceptor, to form a bidirectional spatial light modulator (BSLM) which facilitates the flow of data in the forward and reverse directions. An image can be written from the left side of the BSLM and read from the left or right side of the unit. An image can also be written from the right side and read from the right or left or both sides of the unit. The photoreceptor sums the light image intensities when data is concurrently written from both sides into the photoreceptor.
