Optical color image encryption based on Arnold transform and interference method
Wen Chen,Chenggen Quan,C.J. Tay +2 more
TL;DR: A novel method to encrypt a color image based on Arnold transform (ART) and interference method that encrypts each channel into two random phase masks based on the ART and interfered method is proposed.
Journal ArticleDOI
Shape measurement of small objects using LCD fringe projection with phase shifting
TL;DR: The method developed can also be applied to the measurement of the warp of a small component under thermal loading and is capable of conducting fully automated measurements.
Journal ArticleDOI
Multiple-image encryption by space multiplexing based on compressive sensing and the double-random phase-encoding technique
TL;DR: A new multiple-image encryption and decryption technique that utilizes the compressive sensing concept along with a double-random phase encryption (DRPE) is proposed, which results in a nonlinear encryption system that is able to overcome the vulnerability of classical DRPE.
Journal ArticleDOI
Microscopic surface contouring by fringe projection method
TL;DR: In this article, sinusoidal linear fringes are projected on a micro-component surface by a grating phase shifting projector and a long working distance microscope (LWDM), and the image of the fringe pattern is captured by a high-resolution camera and another LWDM and processed by phase-shifting technique.
Journal ArticleDOI
Phase-retrieval techniques in fringe-projection profilometry
Chenggen Quan,Wen Chen,C.J. Tay +2 more
TL;DR: FTP, phase-shifting and continuous wavelet transform (CWT) are briefly described and discussed and two-dimensional short-time Fourier transform (STFT) is also presented to extract wrapped phase maps.
