Abstract

A high-resolution multi-spectral imaging system provides a powerful tool for research and clinical applications where accurate color acquisition, analysis and/or reproduction is of importance. For example, a spectral analysis of fluorescence activated tumor cells is of interest in the evaluation of photodynamic therapy procedures. In this paper we present a system that is based on a CCD sensor with a spatial resolution of 1024 X 1024 pixels and a liquid- crystal tunable filter. The CCD sensor operates at a maximum framerate of 30 frames per second and the filter which is mounted in the optical path of the imaging sensor has an average bandwidth of 15 nm.
