The earlier infrared sensing, two-colored technique, was further discussed for developing a more general method of measuring temperature quantitatively under near-ambient conditions. The three-colored technique for quantitative temperature measurement is newly proposed by applying three kinds of infrared filters simultaneously. The respective filters concerned have selective wavelength band several μm in width in the range of 7〜14μm. The applicability was confirmed using numerical simulation to allow a parametric study of how the result varies for different values of emissivity corresponding to the individual infrared filters. The new method has a feature which allows quantitative temperature measurement for target surfaces at each picture element without presuming any emissivity, reflectively and ambient conditions, so that it may be useful across various medical or engineering disciplines.In this survey, we investigated the measurement error experimentally, and the adaptability was evaluated in terms of the surround disturbance and directional characteristics on the technique.
