Abstract

The invention discloses a fluid velocity measurement device based on the terahertz high-speed echo effect, which includes a terahertz echo acquisition module and a signal processing module connected with the terahertz echo acquisition module, wherein the terahertz echo acquisition module is used for Generate the source signal and reference signal, and detect the terahertz echo emitted by the source signal through the fluid. The signal processing module is used to obtain the fluid flow rate according to the terahertz echo and the reference signal, which solves the problem of the existing non-contact fluid flow rate device. For the technical problem of low fluid velocity detection accuracy in complex and harsh environments, clever use of the characteristics of strong penetrability of terahertz waves ensures that terahertz signals can be received in complex environments, so as to accurately measure the flow velocity of the measured fluid, and at the same time It has non-contact characteristics, which is of great significance for the flow velocity measurement of fluids in complex environments.

Description

Technical field [0001] The present invention mainly relates to the field of temperature measurement technology, referring to a fluid flow rate temperature measuring device based on the terahertz high speed echo effect. Background technique [0002] THZ (Thahertz) typically refers to electromagnetic radiation in the range of 0.1-10THz. It is located between microwaves and infrared rays in electromagnetic spectroscopy, which is a special area that is excessive in electromagnetic spectrum, and is also a macro The classic theory to the transition area of ​​microscopic quantum theory. In the electromagnetic spectrum, the infrared and microwave technologies on both sides of the terahertz wave section are already mature, but the terahertz wave technology in the transition spectrum is not perfect, mainly because this frequency band is neither fully suitable for processing using optical theory, also It is not entirely suitable for research on microwave theory to form the "terahertz void"....
