Optically assessing body properties

A system for the invasive assessment of properties of a body on at least one sectional surface, composed of at least an image acquisition unit, of an image processing device with at least one output device, and of a cutting tool having at least one blade for making a cut in the body that creates the at least one sectional surface, wherein

• the image acquisition unit has optical sensors for recording optical signals on at least one sectional surface of a cut introduced in the body with at least one blade of the cutting tool, a light unit for the illumination of the sectional surface recorded optically by means of these sensors, and units for the transmission of the sensor signals that have been converted into electrical signals or data to the image processing device,
• the image processing device has units for receiving the signals or data transmitted by the image acquisition unit and is designed to process the received signals or data for at least one of the following objectives:
• visualization of the at least one sectional surface on at least one display,
• creation of reports describing the characteristics of the body along the at least one sectional surface,
• classification of the body in accordance with a classification system,
• derivation of control signals for a subsequent further processing of the body or of the parts that are created therefrom by the execution of the at least one cut
• the image acquisition unit has at least one unit or the image processing device has at least one unit for the digitization of electrical signals of the optical sensors of the image acquisition unit,
• further characterized in that at least the optical sensors of the image acquisition unit are integrated in the at least one blade of the cutting tool, the optical sensors being directed at the at least one sectional surface that is made directly during the cutting operation by the at least one blade of the cutting tool.
