<p>The invention relates to a photoelectric sensor that can detect various kinds of physical characteristics of the light source. It consists of a case, an optical imaging system, a set of photosensitive elements., a analog-digital conversion circuit and a digital analysis circuit. The optical image of the detected light source is projected to a set of photosensitive elements through the imaging system. After each of the set of photosensitive elements is exposed, its exposure value is sent to the digital analysis circuit by analog-digital con:version circuit in order to analyse its magnitude, amount, placement and its change etc. Finally, the various kinds of physical characteristics of the detected light source, for example intensity, radiation scale, location, static or moving, the moving direction and speed, the amount of the light sources are obtained. Simultaneously it can detect at several angles in a relative fixed direction.</p> |
