Mathematical Processing of Quantum Images in a Biphoton Setup via Measurement Reduction

We investigate the possibilities of increasing the measurement accuracy and creating the least-damaging regime of object illumination by mathematical simulation of the process of generating paired images, that is, a ghost image and a regular image, using a new scheme with quantum biphoton generation. It is shown that diffraction and non-unit quantum efficiency of the sensors in traditional ghost imaging cause missing some information carried by the object arm photons. Forming an image of the studied object in the object arm and registering it makes it possible to weaken the influence of these factors on the measurement result when using the developed version of the method of measurement reduction to the form that is typical for measuring the transparency distribution of the object for processing a pair of obtained images.
