In addition to the original purpose of recording clear blur-free images of the objects moving over industrial platforms, it can also be used as a tool for profilometry and automated visual inspection when coupled with proper structured light illumination modules. This paper illustrates a system employing a pulsed laser diode, uniform intensity line generating optics and a high-speed TDI imager for recording structured light patterns from rotating cylindrical objects. Defect or shape information is coded as distortions in a regular grating pattern recorded by the TDI imager. The shape or defect profile is retrieved by employing Fourier transform and scanning spatial phase detection techniques.||Source Title:||Optics and Lasers in Engineering||URI:||http://scholarbank.nus.edu.sg/handle/10635/58766||ISSN:||01438166||DOI:||10.1016/S0143-8166(97)00106-1|
