In this paper, an integrated system based on a phase-shift laser scanning for measuring shape and a imaging spectrograph for measuring color is described. The system is designed for acquisition of large areas, such as chapels or frescoed walls. The phase-shift laser range-finder provides accurate distance measurement, up to 10 meters, pointing at most target surfaces through the measurement of the phase shift. The acquisition of a complete object is performed point by point by a 2D scanning. The imaging spectrograph measures the spectrum of the light coming from on a narrow rectangular region having width and height equal to the image of the entrance slit projected on the object plane. A complete 2D image is acquired by scanning the region in the direction perpendicular to the slit height. The merging of these multiple acquisitions yields the complete spectral and spatial description of the color of the object.
