Journal ArticleDOI
Design of a high-efficiency seven-port beam splitter using a dual duty cycle grating structure.
Fung Jacky Wen,Po Sheun Chung +1 more
TL;DR: A compact seven-port beam splitter which is constructed using only a single-layer high-density grating with a dual duty cycle structure using a simplified modal method to investigate the properties of this grating.
Journal ArticleDOI
Binary image encryption based on interference of two phase-only masks
TL;DR: A very simple method for binary image encryption based on interference of two phase-only masks is proposed without any silhouette problem and may find applications in the information processing field.
Journal ArticleDOI
Use of the circular Dammann grating in angle measurement
Fung Jacky Wen,Po Sheun Chung +1 more
TL;DR: A novel method of angle measurement by borrowing the concept of the circular Dammann grating (CDG) with the advantages of a simple design with superior resolution to within 1 degree, low cost, and compactness is described.
Journal ArticleDOI
Coaxial holographic encoding based on pure phase modulation.
TL;DR: A simple technique for coaxial holographic image recording and reconstruction, employing a spatial light modulator (SLM) modified in pure phase mode, which will have potential applications in areas such as holographic encryption and high-density disk storage systems.
Journal ArticleDOI
Area measurement at long-distance using a circular Dammann grating
TL;DR: A novel method of noncontact mode area measurement at long distance of 11.25 m by borrowing the concept of a circular Dammann grating (CDG) with the advantages of a simple design with good accuracy of better than 3%, low cost, non contact mode, and a more compact design.
