Color holographic wave-front printing technique
2015 IEEE 13th International Conference on Industrial Informatics (INDIN), 2015The paper presents design and implementation of a color wavefront holographic printer for white light viewable holograms of three-dimensional (3D) objects from digital contents. The printed hologram was composed as a two-dimensional (2D) array of elemental holograms. The 3D information was encoded in computer generated holograms displayed in succession

Holographic Inspection Of Printed Circuit Board
SPIE Proceedings, 1986The possibility of using real time holographic interferometry (HI) to detect defects in printed circuit boards has been explored. Initial results indicate that real time HI can reveal some of the most common PC board defects such as solder crack, desoldered junctions, trace separation and components snipped at the soldered joints.

Acquiring spatially varying appearance of printed holographic surfaces
ACM Transactions on Graphics, 2018We present two novel and complimentary approaches to measure diffraction effects in commonly found planar spatially varying holographic surfaces. Such surfaces are increasingly found in various decorative materials such as gift bags, holographic papers, clothing and security holograms, and produce impressive visual effects that have not been previously
