Description

technical field [0001] The invention relates to the field of sensors, in particular to an optical sensor working in a high-temperature environment. Background technique [0002] Optical sensors are sensors that use photosensitive elements to convert optical signals into electrical signals. Its sensitive wavelengths are near the wavelength of visible light, including infrared wavelengths and ultraviolet wavelengths. The light sensor is not limited to the detection of light, it can also be used as a detection element to form other sensors to detect many non-electric quantities, as long as these non-electric quantities are converted into changes in optical signals. Optical sensor is one of the sensors with the largest output and widest application at present, and it occupies a very important position in automatic control and non-electrical measurement technology. [0003] Photosensitive sensors are widely used as detection elements in combustion equipment, but the working envi...
