A Flat Panel Detector is proposed for detecting radiation. Inheriting from plasma display panel structure, the flat panel detector has a potential in low manufacture cost, long life time and wide application prospective. In this work, the structure of the novel flat panel detector is introduced and the detector behavior has been studied with respect to many parameters, including the hole diameter, the operating voltages, the size of the drift region and shadow mask. The results reveal the unique characteristics of the detector and provide guidelines for further modifying the current structure. © 2014 IEEE. Source

A small amount of polyaniline functionalized graphene (G-PANI, 0.03-2.00%) nanosheets was doped into conventional polymer-stabilized blue phase liquid crystals (PS-BPLCs), and the electro-optical property effects were studied. The driving capability of BPLCs can be much improved in that the Kerr constant of BPLCs doped with 0.05 wt% G-PANI is increased by ∼55% compared with that of BPLCs without G-PANI. Meanwhile, this composite exhibits no degradation of electro-optical properties, such as response time, hysteresis and residual birefringence. © 2014 The Royal Society of Chemistry. Source

The Gerchberg-Saxton (GS) algorithm is widely used to calculate the phase-only computer-generated hologram (CGH) for holographic three-dimensional (3D) display. However, speckle noise exists in the reconstruction of the CGH due to the uncontrolled phase distribution. In this paper, we propose a method to suppress the speckle noise by simultaneously reconstructing the desired amplitude and phase distribution. The phase-only CGH is calculated by using a double-constraint GS algorithm, in which both the desired amplitude and phase information are constrained in the image plane in each iteration. The calculated phase-only CGH can reconstruct the 3D object on multiple planes with a desired amplitude distribution and uniform phase distribution. Thus the speckle noise caused by the phase fluctuation between adjacent pixels is suppressed. Both simulations and experiments are presented to demonstrate the effective speckle noise suppression by our algorithm. © 2015 Optical Society of America. Source
