Abstract
Many uses for the Hough transform (HT) require only several θ slices, not the entire 2-D Hough space. A new holographic optical architecture is advanced to achieve this in parallel. The computer-generated holograms and holographic optical elements used are discussed, and laboratory results are provided. As a case study, we consider determining printing skew and other defects on cigarette packs. We also discuss how these holograms can produce the entire 2-D HT space.This publication has 13 references indexed in Scilit:
