Projection beams are emitted from a projection unit. An image generating unit associated with the projection unit generates phase-structured image sequences in close-up by a light-emitting display or at a distance by a projection module and downstream image guides, and transmits the sequences to the projection unit. In this manner, both alternatives allow sequences of phase-structured images, phase-shifted relative to each other, to be projected onto the surface to be measured and imaged by the projection unit, even under very spatially limited conditions. The latter alternative allows a battery-powered, capsule-shaped 3D measurement head to be inserted into cavities to be measured without any feeds (other than the guide wire). In this case, the battery powers both the micro display and the image sensor, wherein the image sensor data representing the reflection of the projected image can be either transmitted wirelessly or stored.
