Title: Method for measuring temperature and emissivity
Inventor: AZUMA HIROMI
IPC: H04N9/04
Filed: 1994-08-01
Abstract: PURPOSE:To provide a method by which the temperature and emissivity of an object can be measured in a non-contacting state. CONSTITUTION:The temperature and emissivity of an object can be found by inputting the output signals of two image pickup devices 1A and 1B having different spectral sensitivity characteristics and the background temperature of the object from a background temperature setting circuit 3. The output signals of the pickup devices 1A and 1B have quadratic relations to the temperature of the object and linear relations to the emissivity of the object from the relational expression between the emissivity and reflectivity of the object in a thermal equilibrium state and the relational expression between the transmission characteristic of an optical system and quantum efficiency of the pickup devices 1A and 1B. Therefore, the temperature and emissivity of the object can be decided from the above-mentioned relations by only using the output signals for the image pickup device 1A and 1B having different spectral sensitivity characteristics and assuming the background temperature of the object.
