Abstract
The position determining device (10) exhibits a mask (16) which can be displaced along an axis (T) located in the reference plane. A light source (20) can be displaced together with the mask (16). A sequence of photocells (26) with a lens (26a) contains photocells (PC1-PC7). The mask (16) contains transparent sections and opaque sections. Planes (P1, P2, P3), in which the radiation-reflecting objects (O1, O2, O3) are located extend in parallel with the said axis (T). The time required by the radiation pattern to pass over a location in the planes (P1, P2, P3) is a measure of the distances (x1, x2, x3). When light source (20) and mask (16) are displaced, the objects (O1 - O3) are successively irradiated by light, with intermediate periods without radiation. During the displacement of the pattern, the sequence of photocells (26) detects an energy reflection by the objects (O1 - O3). An output signal is generated at the rate of the pulse repetition rate and is processed in order to establish the object distance. <IMAGE>
