Abstract

We describe a novel projector design based on interferometric fringe projection. The key component in the projector, a movable micro-mirror, has undergone initial vibration, TVAC and radiation testing, with no observed component degradation. We use multi-frame active stereo as basis for 3D reconstruction, giving 3D measurement standard deviation of 0.2 mm, with 12.5 Hz 3D image capture rate and 3D image resolution of 500 x 500 pixels. The system's low power, small size and component longevity makes it well suitable for space applications.
