MULTIFACTOR MODEL OF AN OPTICAL ENCODING SYSTEM WITH SPATIALLY INCOHERENT ILLUMINATION
A multifactor model of a system of optical encoding with spatially incoherent illumination is proposed. The model takes into account the influence of photosensor noise, changes in the image rasters when passing through the optical system, spurious illumination, and noise of the synthesis of the encoding diffraction optical element on the decoded image quality. It is demonstrated that the proposed model predictions agree well with the optical experiment (the decoding error is within 6%).
