Abstract
Rover-borne laser spectroscopy has traditionally been supported by contextual 2D imaging. We present a low-cost, miniaturized projector designed for the space environment, which is capable of active phase shifting fringe-projection. It consists entirely of individual off-the-shelf optics housed in simple mechanics. Whilst scalable to different applications, it is integrated here inline in a combined NIR microscope / Raman spectroscope to allow construction of highly resolved 3D spatial and chemical maps of astrogeological objects. Requirements, architecture and trade-offs are discussed before calibration and 3D performance results are shown, before 3D measurements from a geological sample are presented.
