NOVELTY - The system has a light source (1), an optical deflecting system (3,4) and an optical imaging system (8), which are all located rotationally about an axis, so that all components of the measuring system can be rotated relative to the stationary cavity or hollow space to be measured. IMAGING AND COMMUNICATION - The measurement system works on the principle of the light intersection method based on triangulation. USE - The measurement system is used for determining inner contours of hollow spaces. ADVANTAGE - The inner contour is determined quickly and completely. The measurement resolution achieved is greater than that possible using known scanning heads and fibre optic sensors. DESCRIPTION OF DRAWING(S) - The drawing shows the measuring system and an object with a bore.
