摘要：The invention relates to a device for the contactless measurement of a distancein relation to a surface which is located inside a narrow gap which is open on one side andhas a maximum width of 5 mm and a minimum depth of 50 mm, said surface defining thenarrow gap together with two lateral walls. The inventive device comprises an opticalsensor unit which is arranged opposite the open narrow gap, at least one structured lightsource which directs a plurality of separated light beams onto the surface, an opticalreceiving unit which detects the light beams which are backscattered onto the surface in atemporally synchronous manner, and an evaluation unit which is used to evaluate thedetected light beams according to the light-section method. The invention also relatesto a preferred use of the device as a light-section sensor for deep-drawing.
