Paper Abstract

Geometric measurements of a surface can be encoded in real-time as a set of fringe images using moire projection techniques. However obtaining numerical values from the encoded surface measurements has not been straightforward. To solve this problem we have developed a phase-shift moire camera that captures in real-time a sufficient number (three) of phase-shifted moire patterns to allow the decoding of the moire patterns to be automated. The RIPS Camera uses three simultaneously produced phase-shifted moire fringe images of a scene (above left) to produce data (above right) that can be reduce to range data.
