一、前言辐射测温是典型的非接触测量法,响应好、温度分辨率高,可广泛用于不可能或者不能满意地用热电偶等作接触测量的场合。然而,在辐射率很低、变化激剧或炉内测温时,可靠性仍然不够。辐射测量时必定牵涉到辐射率和周围杂射光噪声等问题。近几年来,发表了消除辐射率影响的好方 First, the introduction Radiation temperature measurement is a typical non-contact measurement, good response, high temperature resolution can be widely used in impossible or unsatisfactory contact with the thermocouple measurements such occasions. However, the reliability is still not enough when the emissivity is low, the variation is dramatic, or the furnace temperature is measured. Radiation measurements must involve emissivity and ambient light noise and other issues. In recent years, published a good way to eliminate the impact of emissivity
