美国专利US6652468(2003年11月25日公布) 红外气体传感器由红外光源和红外探测器两部分组成。红外探测器仅对红外辐射的变化起作用。在进行测量时,传统的做法是利用一调制盘对来自光源的光进行调制,使热光源与冷调制盘遮光板之间产生大的温度幅度。然后,脉冲辐射便可以被准确计算出来。然而,这种技术需要依赖于昂贵的、不灵活的、易损的设备,而且这种设备采用运动部件,这对于现代电子技术是不适应的。 本发明提供一种用传感器鉴别和测量气体的方法。这里所用的传感器由脉冲辐射制冷红外辐射源、红外探测器、光具和电子部件组成。其中,脉冲辐射制冷
US Patent US6652468 (November 25, 2003 publication) Infrared gas sensor consists of infrared light source and infrared detector of two parts. Infrared detectors only affect the changes in infrared radiation. In making measurements, it is conventional practice to modulate the light from the light source with a modulating plate, creating a large temperature range between the hot light source and the cold plate shutter. Then, the pulse radiation can be accurately calculated. However, this technique relies on expensive, inflexible, fragile equipment, and the use of moving parts in such equipment is not compatible with modern electronic technology. The present invention provides a method of using a sensor to identify and measure gas. The sensor used here consists of a pulsed radiation cooled infrared radiation source, an infrared detector, light fixtures and electronic components. Among them, the pulse radiation cooling
