For the absolute and shade-free shape measurement of 3-D objects with large height discontinuities, a coaxial optical sensor system with a common image plane for pattern projection and observation is proposed. Experimental results are presented that demonstrate the shape measurements of objects with a deep hole and large discontinuities.
