TERAHERTZ RANGE ELECTROMAGNETIC RADIATION MONITORING DEVICE Russian patent published in 2020 - IPC H01L31/00 G01J5/20 

FIELD: physics.

SUBSTANCE: invention relates to monitoring of electromagnetic environment. Terahertz range electromagnetic radiation monitoring device comprises a detecting element arranged in a shielded housing, according to the invention, it is equipped with a terahertz band-pass resonance filter designed to transmit a controlled electromagnetic signal to the detecting element, in the form of a photoconductive antenna, in which the input is connected by a fibre-optic cable to the output of a femtosecond laser, and outputs are connected to first input of synchronous amplifier, microprocessor, outputs of which are connected to first input of femtosecond laser and output of TFT-display module through UART interface bus, with portable personal computer via USB bus or UART interface bus, also has an analogue-to-digital converter built into the microprocessor, the input of which is connected to the output of the synchronous amplifier, a power supply, the output of which is connected through the input of the power controller to the second input of the synchronous amplifier, microprocessor input, TFT display module input and second input of femtosecond laser setup, wherein a screened housing further includes a synchronous amplifier and a microprocessor with a built-in analogue-to-digital converter.

EFFECT: technical result is higher speed and accuracy of measuring electromagnetic signals of terahertz range.
