Abstract

A distributed temperature and pressure integrated optical measurement system includes an optical pressure detection module and a temperature detection module. The sensor probe can be distributed and continuously measure the temperature gradient change on the same axis, and can realize the integrated measurement of pressure. If a single crystal is used as the sensor material, the probe can be used in extremely harsh environments such as ultra-high temperature and strong corrosion. In the case that the probe is in an ultra-high temperature area, the optical collimation system composed of ordinary optical elements can be arranged in a remote low temperature safe area.

Description

technical field [0001] The invention belongs to the cross field of light sensing, space light, material science and material processing technology, relates to a photoelectric detection technology, specifically a sensor that adopts cascaded optical interference cavities to realize integrated measurement of distributed temperature and pressure system. Background technique [0002] Temperature and pressure are two of the most important physical characteristic parameters in industrial production, especially in heavy industry and military industry, it is often necessary to measure these two parameters in extreme environments. The so-called extreme environments usually refer to environments such as ultra-high temperature, strong corrosiveness, ultra-high pressure, and strong electromagnetic interference. For example, in petrochemical synthesis, aviation and aerospace engine operation, smelting, oil drilling and other operations, extreme environments are often encountered. [000...
