    Abstract: To measure the cross-section of an object in a contact-free manner (that is to say without contacting the object) use is made of an optical sensor system and means for causing relative movement of the sensor system and the object being measured, the sensor system comprising at least two emitters which emit respective scanning rays at an angle to one another and directed to respective receivers which supply signals to an evaluation unit upon interruption of each ray by the object and subsequent cessation of said interruption; at least two of said co-operating emitter-receiver pairs are so arranged that their scanning rays (or projections thereof on a common plane parallel to the scanning rays) cross one another and extend at angles to the direction of relative movement.
