Abstract
The invention relates to a method for the contactless measurement of angles or angle modifications, distances or lateral displacements in objects. According to said method, an aperture is transilluminated by means of a ray bundle and after being reflected by a distant reflective element, which generates or is subjected to the angles, angle modifications or lateral displacements that are to be measured, is projected onto a detector surface by an optical system. The image of the aperture on the detector surface is captured, the position of the aperture image is determined in relation to a reference point on the detector surface and the measured value of the angle modification or lateral displacement is calculated using the distance of the centre of the image from the reference point. The invention also relates to an angle or height measuring device.
