Optical color image encryption by wavelength multiplexing and lensless Fresnel transform holograms
Linfei Chen,Daomu Zhao +1 more
TL;DR: This work proposes what it believes is a new method for color image encryption by use of wavelength multiplexing based on lensless Fresnel transform holograms and presents an optical color image coding configuration with multichannel implementation and an optoelectronic color imageryption architecture with single-channel implementation.
Journal ArticleDOI
Optical image encryption with Hartley transforms.
Linfei Chen,Daomu Zhao +1 more
TL;DR: A new method for image encryption based on Hartley transforms that is a real transform and can be realized by spatially incoherent or coherent illumination is proposed and computer simulations prove it is possible.
Journal ArticleDOI
Optical image encryption based on fractional wavelet transform
Linfei Chen,Daomu Zhao +1 more
TL;DR: Based on the fractional wavelet transform (FWT), a novel method for the image encryption is proposed that encrypts the image by two fractional orders and a series of scaling factors and realizes the partial encryption by using this method.
Journal ArticleDOI
Color information processing (coding and synthesis) with fractional Fourier transforms and digital holography
Linfei Chen,Daomu Zhao +1 more
TL;DR: A new method for color image coding and synthesis based on fractional Fourier transforms and wavelength multiplexing with digital holography is proposed, which would improve the security of information encryption.
Journal ArticleDOI
Optical image encryption with redefined fractional Hartley transform
Daomu Zhao,Xinxin Li,Linfei Chen +2 more
TL;DR: A new method for optical image encryption is introduced on the basis of two-dimensional (2-D) generalization of 1-D fractional Hartley transform that has been redefined recently in search of its inverse transform.
