Optoelectrofluidic field separation based on light-intensity gradients

Automatic Layer Separation using Light Field Imaging

We propose a novel approach that jointly removes reflection or translucent layer from a scene and estimates scene depth. The input data are captured via light field imaging. The problem is couched as minimizing the rank of the transmitted scene layer via Robust Principle Component Analysis (RPCA). We also impose regularization based on piecewise smoothness, gradient sparsity, and layer independ...

Measurement of molecular diffusion based on optoelectrofluidic fluorescence microscopy.

This technical note reports a method for measuring the diffusion coefficient of molecules based on an optoelectrofluidic platform. Optoelectrofluidic fluorescence microscopy, which is constructed with an optoelectrofluidic device and a conventional fluorescence microscope, is a useful tool for controlling and detecting local molecular concentration in a fluid with a single light source. When we...

Adaptive Blind Source Separation Based on Intensity Vector Statistics

Light intensity effects on photoinduced charge separation parameters in a molecular triad based on an Iridium(III) bis(terpyridine) unit.

The effect of photon flux on the yield and lifetime of charge separation over the extreme components of a D-Ir-A triad, where D is a triphenyl amine electron donor, A is a naphthalene bis(imide) electron acceptor and Ir is an Ir(III) bis(terpyridine) complex, has been investigated. In usual laboratory conditions, with nanosecond and picosecond laser pulses in the 4-8 mJ range, biphotonic proces...

Panorama Based on Light Field Images

Light field camera captures an array of images by microlens near the detector while traditional camera just takes one 2D picture of a 3D scene via one single lens. Though the resolution is not as good as traditional camera, light field device still brings a lot of advantages in many ways [1,2]. For example, depth detection, post-focus, 4D feature detection or even animated thumbnail 3D camera s...
