A light-weight headworn scanning system of concave mirrors on a wheel, with a detector-capsule for both visible and infrared radiation, the generated signals from incoming radiation being used to convert the scanned object or scene into a touch-felt image on the skin. A fine wire brush revolving with the mirror-wheel distributes amplified electric signals from the detector to a circle of contacts whose wires lead to an individually form-moulded forehead panel or receiver made up of several hundred electro-motive components, each of which represents a particular tiny spot of the scanned scene and will be activated to touch and withdraw from the forehead skin according to the brightness or darkness of that particular spot in the scene. These electro-motive components of special new design make electrical connection in the system by simple insertion in a uniquely constructed panel, and are as readily removed for inspection. Focus is obtained by moving the detector-capsule nearer to or farther from the concave mirrors, and a plane mirror-(s) can be used to reflect rays from them in a backward direction to the detector in order to accommodate focal length in reduced space. A fan revolving with the mirror-wheel moves air to ventilate the space between the tactile component panel and the forehead.
