AN IMAGING DEVICE FOR MULTISPECTRAL ANALYSIS IN THE VISIBLE RANGE
Abstract
The method of characterizing a tunable bench of filter in the visible range and the spectral responsivity of a CCD camera is described. The two instruments are joined to form an image spectroradiometer, the performances of which are estimated taking into account its ability in reconstructing the spectral radiance of the light. The criteria useful to compensate the effect of finite bandwidth of the tunable filter are presented showing the effectiveness of the correction in determining both the spectra and the colorimetric CIE Lxy coordinates of the analyzed coloured samples. The system presents the performance of a good colorimeter-spectroradiometer adding the ability of analyzing a wide surface with a good spatial resolution, contemporarily.
