a A photograph of the sensor that is used. b, c The measured and e, f simulated dependency of the 3D point standard deviation σ3D and point cloud completeness p on the degree of projector defocusing, which is approximated by a Gaussian blur with standard deviation σblur, and the rotational speed ω of the GOBO wheel. d A detailed view of the GOBO wheel of the sensor that is shown in a. Undesired opaque spots, which may negatively affect the measurement accuracy, are clearly recognisable
