DEVICE FOR CONVERTING TERAHERTZ RADIATION TO INFRARED RADIATION Russian patent published in 2024 - IPC G02F2/02 B82B1/00 

FIELD: physics.

SUBSTANCE: invention relates to imaging of terahertz (THz) radiation sources and can be used in designing devices for early diagnosis of skin cancer. Invention can also be used to create devices for detecting objects hidden under the clothes of citizens, at airports, railway stations, stadiums and other public places. Disclosed is a device for converting terahertz radiation into infrared radiation in the form of a matrix which is transparent in the region of converted frequencies of the THz range and in the region of detected frequencies in the infrared range, which contains converters in the form of nanoparticles from a copper-nickel alloy of 47 wt.% of C and 53 wt.% of Ni, uniformly distributed in the volume of the matrix, wherein the nanoparticles have dimensions of 0.9–2.6 nm, and the matrix is made of polystyrene.

EFFECT: high sensitivity of the device for converting terahertz radiation into infrared radiation by THz power owing to reducing the power required to heat the transducers to the operation threshold of the infrared chamber.
