Device and method for measuring gas pressure in sealed glass gas chamber

The invention provides a device and method for measuring the gas pressure in a sealed glass gas chamber, and belongs to the technical field of gas pressure intensity detection. The measuring device comprises a laser used for irradiating a gas to be measured, a beam expanding lens, a sealed glass gas chamber for packaging the gas to be measured, a collecting lens and a photoelectric detector, the light beams emitted by the laser pass through the beam expanding lens and then pass through the glass gas chamber, then pass through the collecting lens and are received by the photoelectric detector.The measuring device detects in a pure-light mode, and compared with a measuring mode in the prior art, the response is fast, and the measuring precision of the measuring device is higher relative tothe heat conduction type measurement. 本发明提供了种封闭玻璃气室内气体压强的测量装置及测量方法，属于气体压强检测技术领域。本测量装置包括用于照射待测气体的激光器、扩束透镜、用于封装待测气体的封闭的玻璃气室、收集透镜和光电探测器，激光器发射的光束经过扩束透镜，之后经过玻璃气室，之后再经过收集透镜，再由光电探测器接收。本测量装置通过纯光方式进行探测，相对于现有技术中的测量方式，响应更快，相对于热传导式测量，本测量装
