Abstract

In this paper, we present a method to estimate the reflected and fluorescent spectral radiance factors of a fluorescent object based on spectrophotometric data without using a monochromator. We use truncated Fourier series to approximate both two spectral radiance factors. Then, based on the measured spectral obtained from a spectroradiometer, the coefficients of the truncated Fourier series are estimated using an weighted least square algorithm. The weighting function is defined as the sum of the CIE standard x, y, and z color matching functions. With the estimated reflected and fluorescent spectral radiance factors, we can predict the color appearance of a fluorescent object under other sources such that the color difference is minimized from viewpoint of human vision.
