Abstract

New computer generated hologram (CGH) recording techniques are discussed and initial demonstrations provided. CGHs are advantageous in fabricating lensless optical systems (with the lens elements recorded on the CGH). Applications include the lensless optical Hough transform (HT) and matched spatial filter (MSF) correlators. These new CGHs allow binary recording of complex functions with a reduced space bandwidth product (SBWP) compared to other techniques.
