Abstract
Apparatus having application to surgical operations has an ultra-violet laser pulse generator (1), an infrared laser pulse generator (3), an optical fibre (11) which transmits these pulses in one direction to the organ (13) and returns the fluorescence emitted by the organ together with reflected infrared radiation. Said returned radiation is detected by two receivers (25 and 20) and a circuit (31) for processing the electric signals delivered by said receivers.
