| Abstract: | A new kind of radiance and temperature measurement instrument were presented. This system measures temperature in real-time, using 0.81 um laser as a radiating source, Si-PIN photodiodeas light receiving sensor, 8031 microprocessor as a controlor. It is composed of optical emitting andreceiving system, signal amplifying and controlling system, and display system. The principle andstructure of this system are introduce. The key technologies and the corresponding solution methods are discussed. Accuracy of this measurement system are analyzed. |
