An optical triangulation technique using a solid state laser diode sourceand detector, providing sub-pixel resolution on a
CCD detector was developed and is discussed. A novel approach to the problem of non-linear accuracy is outlined.
Results of extensive research into improving the accuracy of the device with particular reference to configuration, optical
components, the laser source, linearity, resolution, calibration and interpolation are presented.© (1991) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
