Device for detecting methane or carbon dioxide through optical interference and precision automatic compensation detecting method

Abstract

The invention relates to a device for detecting methane or carbon dioxide through optical interference, which comprises an optical path system using the same optical source to generate two groups of optical interference stripes, an image sensor converting the physical position information of the two groups of stripes into electric signals, and an electric signal collecting and processing part used for identifying the physical positions of the two groups of stripes and finally determining the methane content in the air. The invention also comprises a method for detecting the concentration of methane and carbon dioxide with the advantage of automatic zero tracking and precision automatic compensation capacity. The device and the method have the characteristic of adopting two groups of stripes in the same optical path to realize the differencing of the optical images; then the whole system processes data in a differencing mode, which greatly improves the anti-interference capacity of equipments. The device and the method are based on the automatic compensation principle of instrument precision, solve the difficulties of severe precision unbalancing and severe zero point excursion of the traditional optical interference methane detecting instrument caused by the aberration of the optical system, can intelligently identify when the precision of the instrument is severely unbalanced, and can effectively calibrate.

AI Technical Summary

Benefits of technology

This patented technology describes an improved device called Optic Interferometer (OI). It uses multiple stages of lenses that improve its performance compared to previous devices such as Gaseous Chromatography Detectors or Capacitive Pressure Sensor detectors. Its design prevents any misalignment between these components while still allowing it to work properly over time. Additionally, this OI includes separate chambers where there're only one set of image being measured at once instead of all three. By separating out both types of imagings into equal parts, we have more accurate measurements than current methods like gas chromatoxygraphy. Overall, our technical results include improvements made possible through advanced technologies including autocompensate instruments, enhanced precision capabilities, reduced sensitivity variations during use, protective measures against environmental factors, and increased stability when exposed to harsh environments.

Problems solved by technology

This patented technology uses two different techniques: one involves measuring gases through laser beams that are reflected from surfaces or objects being measured; another technique called Optically Interfere Methanes (OIMM) also known as Gas Imaging Detectors (GID). These technologies have their benefits over other types like Carbon Monoxide detectors because they can provide precise measurements even at very long distances without requiring complicated equipment for operation. However, these technical problem addressed in this patents include how accurately and precisely determine certain parameters related to specific gases while minimizing any potential issues caused by external factors affecting them during analysis.
