Reflection-type holographic disk-type memory using three-dimensional speckle-shift multiplexing
holographic memory reflection-type hologram speckle shift multiplexing
2016/11/22
This review presents a reflection-type holographic memory using three-dimensional(3D) speckle-shift multiplexing. First, the schematic of the proposed memory system was described. Then, experimental d...
Tunable Reflection Bands and Defect Modes in One-Dimensional Tilted Photonic Crystal Structure
Photonic Crystal Structure Photonic Band Gap (PBG) Omnidirectional Reflector Tilted PC Structure De-fect Modes
2013/1/30
We show theoretically that range of reflection bands and defect modes inside the band gap can be tuned by using a one-dimensional tilted photonic crystal (TPC) structure. A TPC structure is similar to...
THE EFFECTS OF LASER REFLECTION ANGLE ON RADIOMETRIC CORRECTION OF THE AIRBORNE LIDAR INTENSITY DATA
Radiometric Correction LiDAR Intensity Data Reflection Angle Surface Normal Land Cover Classification
2014/6/5
Radiometric correction (RC) of the airborne Light Detection And Ranging (LiDAR) intensity data has been studied in the last few years. The physical model of the RC relies on the use of the laser range...
A polarized backlight for LCD illumination is designed and fabricated in which s-polarized light is extracted owing to selective total internal reflection at microstructures in the anisotropic layer. ...

2011/4/28
The paper deals with investigation of the white Lambertian standards by means of optical methods, i.e., the bidirectional reflection distribution function (BRDF) method and the reflectance study with ...
Multiple omnidirectional reflection bands from half-wave layered periodic structures
thin films multilayers filters bandgaps 1D photonic crystals
2011/4/26
The paper is concerned with one-dimensional multilayers that exhibit multiple bands of omnidirectional reflection, which means complete reflection regardless of incidence angle and polarization. The t...
