Paper Abstract

We describe a computer generated hologram (CGH) to produce the Hough transform (HT) with a new output format that eliminates the ambiguity and noise caused by overlapping outputs in the Hough space. The new format HT CGH is designed and fabricated as a multilevel phase CGH which greatly increases the light efficiency and requires less space bandwidth product (SBWP) compared with amplitude HT CGHs reported previously. New format HT phase CGHs have been fabricated and tested in the laboratory and these results are presented. Optical laboratory data obtained using these CGHs are presented for multitarget tracking of point targets.
