HIGH RESOLUTION IMAGING DEVICE IN A LENSLESS CAMERA Russian patent published in 2022 - IPC G02B27/10 

FIELD: optics.

SUBSTANCE: invention relates to the field of optics, in particular to methods and means of optical conversion of electromagnetic radiation, and can be used in the formation of an optical image of objects in miniature lensless cameras. The substance of the invention lies in the fact that a device for forming a high-resolution image in a lensless camera by shadow from radiation on a matrix of detectors, containing a coding mask consisting of holes and jumpers, coded according to a random law, and a detector, also additionally contains an optically coupled reflective prism, separating prism, the second detector, which, like the first one, is made in the form of matrices of charge-coupled devices, to which two analog-to-digital converters are electrically connected in series, each of which is connected to an electronic computer.

EFFECT: increasing the luminous efficiency and improving the quality of the reconstructed image of the original object.
