A novel tri-layer Si-based micro-cantilever thermal infrared (IR) detector with carbon nanotube (CNT) film is fabricated. It is based on the characteristic that the composite micro-cantilever bends in response to incident IR therm

Polarization mode dispersion (PMD) mitigation is performed using an optical 3R (re-amplification, re-shaping, re-timing) regenerator based on electro-absorption modulator (EAM) with wavelength conversion. System performance withou

Statistical distributing and magnitude of the first and second-order polarization mode dispersion (PMD) vectors are evaluated and the timing displacements of its effects on dispersion-managed soliton (DMS) are also given with help

The bipolar phase-shift-keying (BPSK) optical orthogonal codes (OOCs) are inserted into the optical packet format of bit-serial label. The ultra-fast separation of the label and payload is performed through the auto-correlation pu

A new distributed optical fiber sensor system for long-distance oil pipeline leakage and external damage detection is presented. A smart and sensitive optical fiber cable is buried beneath the soil running along the oil pipeline,

A technique for coherent imaging based on spatial frequency heterodyning is described. Three images corresponding to three physical measurements are recorded. For the first measurement, a scene is simply illuminated with a coheren

An additive discussion for the validity of using the weighted information entropy to evaluate the complex degree of infrared (IR) backgrounds is given. Since small targets can be temporarily lost in actual infrared video sequences

A fuzzy bidirectional flow is presented, which performs a fuzzy backward (inverse) diffusion along the gradient direction to the isophote lines (edges), while does a certain forward diffusion along the tangent direction on the con
