A novel approach for an electro-optical sensor is being researched that can image the smallest movements and changes (e.g. perspiration) of the skin surface without contact and with particularly high accuracy (< 100 nm) and frame rate (1 kHz) in a range of 1 cm2 in real time. For this purpose, the state of the art is extended to simultaneous observation of all image points of a 2D image plane using digital signal processing and radar technology. The focus is on validating the sensor principle, first in the laboratory with phantoms, then in medical studies with D02–D05 to prove a diagnostic added value, e.g. to detect stress.
