To develop a multi-channel imaging system based on the principle of a flying spot scanner capable of resolving surface optical characteristics such as roughness, scratches etc. in the presence of surface profile variations. We aim to replace multiple instruments for measuring flatness surface defects etc. with one instrument giving a pseudo-colour output image and a depth image. This will be achieved by decoding light detected at multiple angles from the measured surface. The multi-channel images may be decoded by use of redundancy in the image information and such techniques as principle value decomposition (PVD). Depth information can be estimated by using the constraint that the second differential of depth is zero at all points on the surface. New image processing techniques will be needed to achieve this.The target of the instrument is initially ceramic tile production but there appears to be a need for such a device in other manufacturing fields as well as laboratory applications such as the measurement of electro-phoretic gels and liquid crystal research.
