Description

technical field [0001] The invention mainly relates to the technical field of temperature measurement, in particular to a THz (TeraHertz terahertz) passive radiation temperature measurement device. Background technique [0002] Terahertz wave is an electromagnetic wave with a wavelength of 0.1-10THz, between microwave and infrared. It has great application prospects in biomedicine, security detection, and information communication. At present, the terahertz spectroscopy system is commonly used to process terahertz waves. It is a kind of coherent detection, which can obtain the amplitude and information of terahertz pulses. By performing Fourier transformation on the time waveform, information such as the energy intensity of terahertz emission sources can be obtained. . For objects in a high temperature state, terahertz waves will continue to radiate. By collecting and analyzing the energy intensity of these terahertz waves, it can reflect the real temperature of the measur...
