An experiment has been done to validate the correlation of spectral responsivity of thermal detectors and spectral absorption index of their receiving areas in a visible wavelength region. The detectors were polivinylidene fluoride (PVDF) pyroelectric detectors coated with paints of colors. The paint colors were blue, green, yellow and red.
Each paint color was applied in three different thickness. In all the color detectors, there was good correlation between the relative spectral responsivity and the relative spectral absorptance of the detectors. The correlation factors were more than 0.99. The ratio of the relative spectral responsivity and the relative spectral absorptance of the detector was constant in the wavelength region.
