Abstract
A multi-factor model of an optical encryption system with spatially incoherent illumination is proposed. This model takes into account the influence of the recording photosensor noise, changes in image resoltion during transmission through the optical system, spurious illumination, and noise from the synthesis of the encryption diffraction optical element on the quality of the decoded image. It is shown that the proposed model correlates well with the optical experiment (the deencryption error differs by no more than 6\(\%\)).
