HIGH-RESOLUTION IMAGING DEVICE Russian patent published in 2022 - IPC G02B21/04 G02B21/18 G02B27/10 

FIELD: optical technology.

SUBSTANCE: invention relates to the field of optics, to methods and means of optical conversion of electromagnetic radiation and can be used in the formation of optical images of objects in miniature lens-free cameras. The present invention relates to methods for converting images of objects observed by miniature lens-free systems. The essence of the invention lies in the fact that a high-resolution imaging device in a lens-free camera based on the shadow of radiation on a detector matrix containing a coding mask consisting of holes and jumpers encoded according to a random law, and a detector, also additionally contains an optically coupled second coding mask inverse to the first coding mask, two reflective prisms, two separating prisms, a matrix based on devices with charge coupling as a detector, to which an analog-to-digital converter and a computer are connected electrically.

EFFECT: increase in light efficiency and an improvement in the quality of the restored image of the original object.
