Paper Abstract

Near infrared and visible spectroscopic imaging systems were developed which are able to acquire spectroscopic images of samples at a distance, completely without contact. These imaging systems were used to analyze two color test samples and one 15th Century drawing from the Winnipeg Art Gallery. Spectra extracted from the quantitative test sample showed good linearity with ink levels across the visible wavelengths. By using wavelength images which match the wavelength sensitivities of the human eye, color reconstructed RGB images can be created with good color fidelity. Because of its ability to penetrate through some art pigments and inks, near infrared spectroscopic imaging was used to investigate lead-point underdrawings in ancient drawings in order to understand the artistic process better.
