Abstract
The invention discloses a THz passive radiation temperature measurement method, which collects the terahertz emitted by the measured high-temperature source by obtaining the installation deflection angle of the probe used for collecting the terahertz emitted by the measured high-temperature source, and extracts the terahertz according to the terahertz Frequency domain characteristic peak value, according to the terahertz frequency domain characteristic peak value, installation deflection angle and detection distance, the energy factor strongly related to the real temperature of the measured high temperature source is obtained, the mapping function between the energy factor and the temperature is obtained, and the measured value is calculated according to the mapping function The temperature value of the high-temperature source solves the technical problem of low detection accuracy of the temperature of high-temperature objects in the existing non-contact temperature measurement method in complex and harsh environments. Receive the terahertz signal, so as to accurately measure the temperature of the high-temperature source under test, and at the same time have the characteristics of non-contact, which is of great significance for the temperature measurement in the complex environment of high-temperature objects.
Description
technical field [0001] The invention mainly relates to the technical field of temperature measurement, in particular to a THz (TeraHertz) passive radiation temperature measurement method. Background technique [0002] Terahertz wave is an electromagnetic wave with a wavelength between microwave and infrared. Generally speaking, the terahertz wavelength is between 0.1 and 10 THz. Terahertz waves have many unique advantages. In terms of imaging, it can penetrate specific materials and directly observe the internal information of objects; in terms of communication, it can obtain unlimited transmission speeds of 10GB / s; in terms of radiation, it carries huge The energy can boil water instantly. The above characteristics make terahertz have 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 t...
