Abstract
An optical sensor chip, especially for an optical jamming protection device has a one-dimensional or two-dimensional array of photo-sensitive elements, especially photodiodes, a number of pre-processing switching circuits for respectively processing a detection signal of each element, and a programmable interface between the array and the pre-processing switching circuits, a pre-processing switching circuit being associable with each element by the interface. An optical jamming protection device has an emitter unit which is designed in such a way as to emit radiation in a spatial area, a detector unit for detecting a radiation field from the spatial area, and a control unit designed to identify an obstacle in a pre-determined monitoring region in the spatial area, by evaluating output signals of the detector unit. To this end, the detector unit comprises an above-mentioned sensor chip.
