Abstract

A system and method for analyzing matter by computer analysis of electrical signals generated by sensing radiation reflected from matter (i.e. tissue, cells, liquid, gaseous or solid particles in a liquid or gas) and/or generated due to fluorescence. In one embodiment, a short pulse of laser radiation is directed at matter also scanned by an electro-optical scanning means to generate image signals. Fluorescent radiation and reflected radiation generating image signals, generate respective variable electrical signals which are computer processed and analyzed to detect and determine the chemical and/or biological composition of the matter. A television camera scans the matter and generates video signals for computer processing and analysis. Simultaneously or sequentially, pulsed laser energy is directed against plural locations of scanned matter, wherein each of such pulses generates a short duration of fluorescent energy in different select portions of the matter under analysis. Fluorescing light is photoelectrically detected generating variable electrical signals for each portion of fluorescing matter, which signals are computer processed and analyzed along with signals output by the television camera to provide information used to intelligibly indicate: (a) composition of such matter, (b) presence of one or more chemical and/or biological agents in such matter, (c) whether the matter is defective or diseased or, (d) a combination of such indications. The liquid may be any body fluid. Manipulators are provided to move the TV camera, lasers, sensors and treatment lasers and/or surgical instruments.
