Information Encryption Based on Using Arbitrary Two-Step Phase-Shift Interferometry
Deterministic Phase-Encoded Encryption Arbitrary Two-Step Phase-Shift Interferometry Lenticular Lens Array
font style='font-size:12px;'>
2013/1/30
A deterministic phase-encoded encryption system is proposed. A lenticular lens array (LLA) sheet with a particular LPI (lenticular per inch) number is chosen as a modulator (key) instead of the random...
Phase Stable RF-over-fiber Transmission using Heterodyne Interferometry
Radio frequency photonics Fiber optic links subsystems
font style='font-size:12px;'>
2015/6/4
We demonstrate stable transmission of 3GHz over 300m of fiber with less than 0.017 degree (17fs) RMS phase error. An interferometer measures optical phase delay, providing information to a feed-forwar...
Measurement of Fiber Chromatic Dispersion Using Spectral Interferometry with Modulation of Dispersed Laser Pulses
Chromatic Dispersion Spectral Interferometry Modulation Dispersed Laser Pulses
font style='font-size:12px;'>
2015/7/16
We propose and experimentally demonstrate a simple accurate method for fiber dispersion measurement based on modulation of laser pulses stretched by the tested fiber. The spectral interferometry is im...
Optical Coherence Tomography with Spectral Interferometry and Analysis on Extraction of Spectroscopic Information
Optical coherence tomography Spectral interferometry Spectroscopic
font style='font-size:12px;'>
2009/6/12
Optical coherence tomography (OCT) working in the Fourier frequency domain, rather than in the time domain, can provide a coherence function of light scattered from a bulk sample at one exposure witho...
The application of the self-adaptive tracking method to the sinusoidal phase modulating interferometry
sinusoidal phase modulation surface profile measurement
font style='font-size:12px;'>
2011/5/6
In this paper, we analyze theoretically the accuracy of the surface profile measurement in a sinusoidal phase modulating interferometer, derive the relative error formula, and investigate the influenc...
The interferometry based on regular lattice of optical vortices
optical vortex vortex lattice
font style='font-size:12px;'>
2011/5/4
The optical vortices are point phase dislocations. The point where the phase is undetermined is called a vortex point. The lattice of optical vortices can be generated by the interference of three or ...
Differential interferometry in planar waveguide structures with ferronematic layer

font style='font-size:12px;'>
2011/4/26
The paper presents a differential interferometry phenomenon in a planar optical structure, which uses a ferronematic layer of a liquid crystal. This layer changes propagation conditions for TM modes i...
Application of the 3-frame interferometry and the crater replica method for investigation of laser accelerated macroparticles interacting with massive targets in the Prague Asterix Laser System (PALS) experiment
