Photoacoustic imaging method based on arc-direction compressed sensing and multi-angle observation [作者：Sun, MJ; Feng, NZ; Shen, Y; Shen, XL; Ma, LY; Li, JG; Wu, ZH,期刊：OPTICS EXPRESS, 页码：14801-14806 , 文章类型： Article，,卷期：2011年19-16] In photoacoustic imaging (PAI), the photoacoustic (PA) signal can be observed only from limit-view angles due to some structure limitations. As a result, data incompleteness artifacts appear and some image details lose. ... Sparsity based sub-wavelength imaging with partially incoherent light via quadratic compressed sensing [作者：Shechtman, Y; Eldar, YC; Szameit, A; Segev, M,期刊：OPTICS EXPRESS, 页码：14807-14822 , 文章类型： Article，,卷期：2011年19-16] We demonstrate that sub-wavelength optical images borne on partially-spatially-incoherent light can be recovered, from their far-field or from the blurred image, given the prior knowledge that the image is sparse, and on... Enhanced bandwidth and reduced dispersion through stacking multiple optical metamaterials [作者：Escarra, MD; Thongrattanasiri, S; Charles, WO; Hoffman, AJ; Podolskiy, VA; Gmachl, C,期刊：OPTICS EXPRESS, 页码：14990-14998 , 文章类型： Article，,卷期：2011年19-16] All-semiconductor, highly anisotropic metamaterials provide a straightforward path to negative refraction in the mid-infrared. However, their usefulness in applications is restricted by strong frequency dispersion and li... Preventing occurrence of disclination lines in liquid crystal lenses with a large aperture by means of polymer stabilization [作者：Hsu, CJ; Sheu, CR,期刊：OPTICS EXPRESS, 页码：14999-15008 , 文章类型： Article，,卷期：2011年19-16] Liquid crystal (LC) lenses with a circularly hole-patterned electrode possess excellent characteristics in optical performance, especially for the capability of tunable focal lengths. But, non-uniformly symmetrical elect... Sample drift correction in 3D fluorescence photoactivation localization microscopy [作者：Mlodzianoski, MJ; Schreiner, JM; Callahan, SP; Smolkova, K; Dlaskova, A; Santorova, J; Jezek, P; Bewersdorf, J,期刊：OPTICS EXPRESS, 页码：15009-15019 , 文章类型： Article，,卷期：2011年19-16] The recent development of diffraction-unlimited far-field fluorescence microscopy has overcome the classical resolution limit of similar to 250 nm of conventional light microscopy by about a factor of ten. The improved r...
