This paper gives a review of the work carried out in the field of spectral imaging at the University of Joensuu. First we describe a spectral imaging system constructed in the University of Joensuu during last year. The system uses a spectral camera composed of an imaging spectrograph coupled to a CCD B/W matrix camera and an XY-table for the object scanning. We also consider fundamental aspects of metameric color reproduction and we describe a simple method for image reproduction by using a CRT display or other additive devices. In the last part of this paper we give an example of one application: the spectral imaging and color reproduction of icons from the middle of the 19^th century.
