A measurement system of infrared, Raman and laser three-channel point-to-point real-time fusion

Abstract

An infrared, Raman and laser three-channel point-to-point real-time fusion measurement system, the system includes a deep ultraviolet laser, a gate control circuit, a Raman optical imaging ICCD, a laser imaging CCD, an infrared outer plane detector, and a corresponding Raman Long-pass filter, ultraviolet laser filter, infrared filter, etc.; the system uses laser ranging to map the distance of the target point, by calculating the time for the laser to reach the target point and return to the detector, and through precise control The gate control circuit realizes the switching action of the ICCD receiving gate, and realizes the imaging of the Raman scattered light on the target point. The system can be used to measure the gas composition, particle size and temperature of the target point by telemetry.

Description

technical field [0001] The invention relates to a measurement system for point-to-point real-time fusion of infrared, Raman and laser three channels, in particular to a deep-ultraviolet laser laser, a laser imaging CCD, a gate control circuit, and a control circuit controlled by the circuit in a casing. A three-channel measurement system composed of Raman scattered light imaging ICCD and infrared outer plane detector can realize point-to-point fusion. Background technique [0002] At present, the measurement of air pollutants is through the method of pumping and sampling, and the pollutants are detected by gas chromatography, mass spectrometry, far-infrared absorption spectrometer, near-infrared absorption spectrometer, gas sensing detector, etc. For these traditional measurements, the material must be sampled and then introduced into a light-shielded observation chamber for measurement. The measurement speed is slow, it is impossible to sample some high temperature areas, ...

AI Technical Summary

Problems solved by technology

The measurement speed is slow, and it is impossible to sample some high-temperature areas, and it is impossible to achieve point-to-point fusion measurement of characteristic pollutants, particulate matter and temperature in the atmosphere, let alone hierarchical measurement in the atmospheric environment

[0003] The invention patents related to Raman measurement that we have seen so far include: Patent Publication No. 107449767A, Authorized Announcement No.: 104713865B, Authorized Announcement No.: 104713865B, etc. These patents cannot realize three-channel point-to-point fusion measurement in the atmosphere. It is impossible to realize layered measurement and long-distance telemetry in the atmosphere, and the measurement distance of these instruments is short, and can only be carried out in the environment of a vacuum chamber
