摘要

In this study we analyze the influence of the illuminant on the reconstruction of spectral reflectance curves in the near infrared region of the spectrum. We have tested several methods based on multispectral imaging that permit us to obtain the spectral reflectance of samples from measurements performed with a CCD camera. Using numerical simulation, we have analyzed the number and shape of the optimum filters that need to be used in the acquisition channels in order to obtain good spectral reconstructions under a great number of different lighting conditions. Finally, we have studied the influence of the illuminant on the quality of the reconstruction using a set of commercially available filters which are similar to the optimum filters obtained from the simulations. Our results show that the reconstruction does not depend strongly on the illuminant used. This indicates that with the same set of filters we can obtain good reconstructions for different types of illuminant.
