Short summary
We present a digital holographic sensor system that is capable of measuring the complete topography of machined components with sub-micrometer precision directly inside a tooling machine. This contribution includes detailed information about the architecture of the wireless interferometric sensor HoloPort. Experimental results on milled parts show the performance of the system and illustrate possible inline applications as well as future perspectives for the sensor.
