Controlling logical operations with images in accumulated echo holography using the effects of information locking and erasing

The possibility of implementing logical operations with images using the accumulated echo hologram in the presence of external spatially inhomogeneous electric fields is considered. It is shown that the photon echo locking effect makes it possible to control the execution of logical operations (from the union of sets to the symmetric difference and their superposition), as well to control their form by varying the values of the gradients of external spatially inhomogeneous electric fields and the phase difference between pairs of pulses.
