Since several years ENEA�s Artificial Vision laboratory is involved in electrooptics systems development. In the last period the efforts\r\nare concentrated on cultural heritage remote diagnosis, trying to develop instruments suitable for multiple purposes concerning\r\nrestoration, cataloguing, and education. Since last five years a new 3D (three-dimensional) laser scanner prototype (RGB-ITR)\r\nbased on three amplitude-modulated monochromatic laser sources mixed together by dichroic filters is under development. Five\r\npieces of information per each sampled point (pixel) are collected by three avalanche photodiodes and dedicated electronics: two\r\ndistances and three target reflectivity signals for each channel, red, green, and blue. The combination of these pieces of information\r\nopens new scenarios for remote colorimetry allowing diagnoses without the use of scaffolds. Results concerning the use of RGBITR\r\nas colorimeter are presented.
