Multiplicative-regularized subspace technique to solve high contrast inverse scattering problems

2016 Progress in Electromagnetic Research Symposium (PIERS), 2016
In this talk, we will propose a new optimization scheme for solving electromagnetic inverse scattering problems. In the inverse scattering problemthe physical properties of hidden targets, i.e., the permittivity and/or permeability can be retrieve from the measured scattering data excited by several incidences.

A novel WFS technique for high-contrast imaging: Phase Sorting Interferometry (PSI)

SPIE Proceedings, 2008
High-contrast adaptive optics (AO) observations near stars have to contend with the telescope's diffraction halo, a rapidly-changing cloud of residual atmospheric speckles, and a host of faint but persistent quasi-static speckles caused by various imperfections and aberrations.

48.4: Development of High‐Contrast CRT Based on Nano Pigment Screen Technique

SID Symposium Digest of Technical Papers, 2005
Abstract We have developed the NPSCN (Nano Pigment Screen) technique, a new style phosphor screen and successfully applied it to the CRT TVs. The technique significantly improved contrast, color gamut and body color in comparison to the previous CRTs without any additional process or investment cost.

Accurate nanofabrication techniques for high-index-contrast microphotonic devices

2005
High-refractive-index-contrast microphotonic devices provide strong light confinement allowing for sharp waveguide bends and small dielectric optical resonators. They allow dense optical integration and unique applications to optical filters and sensors but present exceptional complications in design and fabrication.
