Abstract

The invention discloses a THz passive radiation temperature measuring device, which includes a terahertz energy acquisition module, which is used to collect terahertz emitted by a high-temperature source to be measured, and extract the characteristic peak value of the terahertz frequency domain according to the terahertz, and the high-resolution visible light installation deflection angle The detection module is used to detect the deflection angle generated by the THz passive radiation temperature measurement device during the installation process. The distance detection module is used to measure the straight-line distance between the THz passive radiation temperature measurement device and the measured high temperature source. Multi-source fusion algorithm processing The module is used to receive the characteristic peak value, deviation angle and straight-line distance in the terahertz frequency domain, and obtain the temperature value of the measured high-temperature source according to the characteristic peak value, deviation angle and straight-line distance in the terahertz frequency domain, which solves the problem of the existing non-contact temperature measurement The device has a technical problem of low temperature detection accuracy of high-temperature objects in complex and harsh environments. By cleverly using the characteristics of strong penetrability of terahertz waves, it can still receive terahertz signals in complex environments, so as to accurately detect the high-temperature source under test. temperature measurement.

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...
