摘要:
A gas detector (100) for remote gas detection in a target region (106) comprises a light source (102) for emitting a light beam (110) into the target region and a light sensor (112) for sensing light returning therefrom. The light beam is wavelength- modulated around an absorption wavelength of the gas. A controller (108) is operatively connected to the light sensor for detecting a presence of the gas on a path of the light beam based on returning light sensed by the light sensor. An indicator (124) that is operatively connected to the controller indicates the presence of the gas. A scanning device (104) is arranged with respect to the light source so as to scan the light beam through the target region, and with respect to the light sensor so that the light sensor receives the returning light via the scanning device. The indicator cooperates with the scanning device to indicate a position of the gas in the target region.

用于在目标区域(106)中进行远程气体检测的气体检测器(100)包括用于将光束(110)发射到目标区域中的光源(102)和用于感测从其返回的光的光传感器(112)。 光束围绕气体的吸收波长进行波长调制。 控制器(108)可操作地连接到光传感器,用于基于由光传感器感测到的返回光来检测在光束的路径上的气体的存在。 可操作地连接到控制器的指示器(124)指示气体的存在。 相对于光源布置扫描装置(104),以扫描通过目标区域的光束,并相对于光传感器扫描,使得光传感器经由扫描装置接收返回光。 该指示器与扫描装置配合以指示气体在目标区域中的位置。
