The image restoration process is an important part of wave-front coding technology. Using wave-front coding makes the modulation transfer function(MTF) values of the optical systems change little over a range of several times the depth of focus  which means the system MTF is quite insensitive to defocus  and there is no zero in the passband. So we can design a single filter for the restoration of images in different defocus positions. However  it's hard to avoid noise during image acquisition and transmission processes. These noises will be amplified in the image restoration  especially in the high frequency part when the MTF drop is relatively low. The restoration process significantly reduces the system signal to noise ratio this way. Aimed at the problem of noise amplification  a new algorithm was proposed which incorporated wavelet denoising into the iterative steps of Lucy-Richardson algorithm. Better restoration results were obtained through the new algorithm  effectively solving the noise amplification problem of original LR algorithm. Two sets of identical triplet imaging systems were designed  in one of which the cubic-phase-plate was added. Imaging experiments of the manufactured systems were carried  and the images of a traditional system and a wave-front coded system before and after decoding were compared. The results show that the designed wave-front coded system can extend the depth of focus by 40 times compared with the traditional system while maintaining the light flux and the image plane resolution. 2010 Copyright SPIE - The International Society for Optical Engineering.   Two-dimensional air-bridged silicon photonic crystal slab devices 期刊论文  OAI收割 PHYSICA STATUS SOLIDI A-APPLICATIONS AND MATERIALS SCIENCE, 2010, 卷号: 207, 期号: 12, 页码: 2715 Gan, L; Zhou, CZ; Wang, C; Liu, RJ; Zhang, DZ; Li, ZY 收藏  |  浏览/下载：38/0  |  提交时间：2013/09/23 CHANNEL DROP FILTER  WAVE-GUIDES  BAND-GAPS  LIGHT  PROPAGATION  EMISSION  DEFECT   Design of a Compact Photonic-Crystal-Based Polarization Channel Drop Filter 期刊论文  OAI收割 ieee photonics technology letters, 2009, 卷号: 21, 期号: 9-12, 页码: 739-741 作者:  Zhang, Wenfu;  Liu, Jihong;  Zhao, Wei 收藏  |  浏览/下载：90/0  |  提交时间：2011/10/08 Photonic crystal (PhC)  polarization and wavelength-division multiplexing (PWDM)  polarization channel drop filter (PCDF)   Design and fabrication of a photonic crystal channel drop filter based on an asymmetric silicon-on-insulator slab 期刊论文  iSwitch采集 Journal of nanoscience and nanotechnology, 2009, 卷号: 9, 期号: 2, 页码: 974-977 作者:  Yu, Hejun;  Yu, Jinzhong;  Yu, Yude;  Chen, Shaowu 收藏  |  浏览/下载：71/0  |  提交时间：2019/05/12 Photonic crystal (pc)  Channel-drop filter  Silicon-on-insulator (soi)   High-Q Microcavity in Two-Dimensional Diamond Photonic Crystal Thin Films Realized via a Mode Gap 期刊论文  OAI收割 CHINESE PHYSICS LETTERS, 2009, 卷号: 26, 期号: 9 Zhou, CZ; Xiong, ZG; Li, ZY 收藏  |  浏览/下载：33/0  |  提交时间：2013/09/17 DROP FILTER   Design and Fabrication of a Photonic Crystal Channel Drop Filter Based on an Asymmetric Silicon-on-Insulator Slab 期刊论文  OAI收割 journal of nanoscience and nanotechnology, 2009, 卷号: 9, 期号: 2, 页码: 974-977 Yu HJ; Yu JZ; Yu YD; Chen SW 收藏  |  浏览/下载：227/48  |  提交时间：2010/03/08 Photonic Crystal (PC)  Channel-Drop Filter  Silicon-on-Insulator (SOI)   Multichannel filters via Gamma-M and Gamma-K waveguide coupling in two-dimensional triangular-lattice photonic crystal slabs 期刊论文  OAI收割 APPLIED PHYSICS LETTERS, 2008, 卷号: 93, 期号: 24 Liu, YZ; Liu, RJ; Feng, SA; Ren, C; Yang, HF; Zhang, DZ; Li, ZY 收藏  |  浏览/下载：42/0  |  提交时间：2013/09/18 CHANNEL DROP FILTER
