Journal ArticleDOI
Security and encryption optical systems based on a correlator with significant output images
TL;DR: An improved optical security system based on two phase-only computer-generated masks is proposed, capable of identifying the type of input mask according to the corresponding output image it generates.
Journal ArticleDOI
Computer-generated holograms of three-dimensional realistic objects recorded without wave interference
TL;DR: This work proposes a method of synthesizing computer-generated holograms of real-life three-dimensional (3-D) objects by using an ordinary digital camera to record several projections of the 3-D object from different points of view.
Journal ArticleDOI
Three-dimensional pattern recognition with a single two-dimensional synthetic reference function.
Youzhi Li,Joseph Rosen +1 more
TL;DR: A novel, to the authors' knowledge, method of distortion-invariant three-dimensional (3-D) pattern recognition that is able to identify and locate any true-class object in the 3-D scene.
Journal ArticleDOI
Object recognition using three-dimensional optical quasi-correlation
Youzhi Li,Joseph Rosen +1 more
TL;DR: A novel method of three-dimensional (3-D) object recognition is proposed, where several projections of a 3-D target are recorded under white-light illumination and fused into a single complex two-dimensional function.
Journal ArticleDOI
Three-dimensional optical correlator with general complex filters
Youzhi Li,Joseph Rosen +1 more
TL;DR: A new type of electro-optical three-dimensional (3-D) correlator is proposed and demonstrated that is a hybridization of the joint transform and the VanderLugt correlators, and, as such, it allows correlations to be made between 3-D real-world objects and 2-D general complex functions.
