Optical image encryption based on diffractive imaging
Optics Letters, 2010In this Letter, we propose a method for optical image encryption based on diffractive imaging. An optical multiple random phase mask encoding system is applied, and one of the phase-only masks is selected and laterally translated along a preset direction during the encryption process.

In this chapter, we discuss two subjects in which diffraction is the dominant process in image formation. The first argument, developed in the first two sections, is the Abbe theory of image formation. The theory is valid in general, but is easier to understand under conditions of coherence.

After a brief introduction to Fourier optics in the previous chapter, we now return to imaging with incoherent light. In Chapter 2 geometrical optics was used to describe image formation and location. Diffraction effects were neglected, and distortions from ideal image quality were attributed to chromatic and spherical aberrations.
