发明名称 ERROR SOURCE RADIANCE OPTICAL FILTERING METHOD AND SYSTEM IN INFRARED RADIATION THERMOMETER
摘要 An error source radiance optical filtering method and a system in an infrared radiation thermometer are provided to secure measurement accuracy and reliability through removal of an error source in measurement environment by employing a distance selecting filter. In an error source radiance optical filtering system, a front lens(5) collects infrared horizontal light reflected or irradiated from an object to be measured(1) or irradiated by an intermediate medium, and transfers the collected light. A pin-hole(6) accepts only the infrared light irradiated from the object to be measured among the infrared light transferred from the front lens. A rear lens(7) transforms the infrared light passing through the pin-hole to the horizontal light in the same specification with the front lens. A collecting lens(8) collects the light transferred from the rear lens. A Pyrometer(9) measures a temperature of the light passing through the collecting lens.
