The content of pigments such as chlorophylls, carotenoids and anthocyanins determines fruit colour and its appearance. These pigments are strictly related to the physiological conditions and their variation can give information about health of fruit. The application of Laser Induced Fluorescence (LIF) and reflectance imaging spectroscopy for visualisation of the pigments distribution over the fruit surface is described. The hyperspectral measurements were performed on healthy orange fruit and fruit inoculated by Phytophthora citrophthora (2x104sporangia/ml) and Penicillium italicum (2x106 spores/ml) two important post-harvest pathogens. The Nd:YAG laser fluorometer (
