Bi-stable image storage apparatus for storing, interrogating, and erasing two-dimensional binary images represented by arrays of light and dark areas. The storage apparatus comprises a pair of image amplifiers, preferably, inverting amplifiers, coupled together into a closed loop optical circuit such that the output of one device will be read into the other device. As long as the gain of the circuit is greater than one the circuit will drive itself to saturation and store an image optically applied thereon. The system provides a very inexpensive circuit for storing images, and can be used in a wide variety of processing and display applications.
