In particular, we investigate the coherence length in such fields, and demonstrate that it can be shorter than the wavelength of the propagating field above the dielectric surface. The higher the refractive-index contrast at the interface is, and the closer to the surface the field is considered, the shorter is the coherence length. Physical explanation for this behavior analogous to the generation of incoherent light in a multimode gas laser is provided. We also assess the degree of polarization in evanescent fields by using a recent three-dimensional formulation.","PeriodicalId":201478,"journal":{"name":"2010 9th Euro-American Workshop on Information Optics","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131552292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventionally 3D microscopy is achieved using two beam interference techniques, which requires adjustment of the beam for high quality interference fringes as well as is more prone to external vibrations. Here we discuss a single beam 3D microscopic technique. The technique works by sampling the volume speckle field generated by putting a diffuser in the path of the probe beam passing through the object at several axial planes and computing the complex amplitude of the object wavefront using angular spectrum approach towards scalar diffraction theory.","PeriodicalId":201478,"journal":{"name":"2010 9th Euro-American Workshop on Information Optics","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125097949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically the optical phase shift induced by the specimen on the transmitted wave front can be regarded as a powerful endogenous contrast agent, depending on both the thickness and the refractive index of the sample. The quantitative phase images allow the derivation of highly relevant cell parameters, including dry mass density and spatial distribution. Thanks to a decoupling procedure, cell thickness and intracellular refractive index can be measured separately. Consequently, cell morphology, shape as well as cell membrane fluctuations can be accurately monitor. As far as red blood cell are considered, Mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC), two highly relevant clinical parameters, have been measured non-invasively at a single cell level. The DHM nanometric axial and microsecond temporal sensitivities have permitted to measure the red blood cell membrane fluctuations (CMF) over the whole cell surface. In addition, the development of live-cell multimodality microscope combining fluorescence with digital holographic microscopy is presented. The biophysical cell parameters derived from the quantitative phase information in combination with the numerous different specific fluorescent cellular probes allow to this multimodality microscope to address various important issues in cell biology.","PeriodicalId":201478,"journal":{"name":"2010 9th Euro-American Workshop on Information Optics","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130029625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike iterative methods, spectral shearing interferometry provides complete real-time information of ultra-short optical signals. Spectral interferometry resolved in time (SPIRIT) is a passive and self-referenced characterization technique that has shown to be suitable for a variety of pulse conditions. SPIRIT Wideband represents a novel configuration aimed for the measurement of a few optical cycle pulses. We present the experimental scheme of SPIRIT Wideband and report preliminary experimental results dealing with the characterization of a few femtosecond pulses.","PeriodicalId":201478,"journal":{"name":"2010 9th Euro-American Workshop on Information Optics","volume":"33 7-8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131882360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of this restriction, conventional 3D displays can be used with digital holographic data. However when using conventional 3D displays, holographic data has to be processed correctly to meet the requirements of the display. A unique property of digital holograms, namely that a single hologram encodes multiple perspectives, can be used to achieve this goal. Reconstructions from digital holograms at different perspectives are processed further to meet the requirements of the conventional 3D display, which are typically based on stereoscopic images of the scene.","PeriodicalId":201478,"journal":{"name":"2010 9th Euro-American Workshop on Information Optics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123116778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show that in the forward direction cloaking is achieved for any object slab and incident field, whereas in the backward direction cloaking is possible at least for self-imaging fields. In both cases the scattering potential of the cloak slab depends on that of the object slab. The method of object-dependent cloaking using weak slab scatterers can be a useful addition to existing cloaking methods, for instance, in atmospheric optics and biophotonics.","PeriodicalId":201478,"journal":{"name":"2010 9th Euro-American Workshop on Information Optics","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133480148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
