Optic-electronic method recognising and position objects - on a series of light sensitive layers

摘要

Optic/electronic arrangement has light sensitive layers with filters (4) whose translucence performs one or more functions. The layers are divided into electrically isolated sections. Its signals serve for sizing and positioning of object (1), and are still further processed. The signals from layer (5) are interconnected; F1 and F2 are zero when the axis of the system points to the centre of the image; and F3 will be zero when the cross of the coordinates for the optic system is covered by the main axis of the image. One filter is used in which the translucence assumes a monotone radial.
