The formula for the period in the combined objects with the center of the cylinder on the axis of the camera is obtained. Compared to objects with parts of similar curvature (two planar surfaces or two halves of a cylinder), the moiré patterns in the combined objects are diverse: particularly, the period of the moiré patterns can have up to two maxima across the surface of the cylinder. Experiments with the camera on the coordinate axis confirm the theory. An overall picture of the patterns is given in the parameter space. The results can be applied to nanoparticles and measurements.","PeriodicalId":501620,"journal":{"name":"Journal of the Optical Society of America A","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142249293","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}

However, a key limitation has been their confinement to fully coherent light beams. In this work, we introduce a new, to the best of our knowledge, concept called the non-separable partially coherent vector (NSPCV) beam, which exhibits unique non-separable correlation between polarization and partially coherent spatial modes, a correlation marked by the presence of the twist phase in the coherence degree of freedom. We investigated their transmission properties using polystyrene bead suspensions. Results show NSPCV beams exhibit superior stability compared to Gaussian beams. This work not only broadens the scope of non-separable optical beams but also promises higher robustness in strongly scattering media.","PeriodicalId":501620,"journal":{"name":"Journal of the Optical Society of America A","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142181934","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}

Highland, Albert Rancu, Hillel Price, Steven M. Parker, Meghan Reynolds, Brenton D.

While fluorescence microscopy has been used for aiding mechanotransduction research due to its molecular sensitivity, the ability of quantitative phase imaging (QPI) to visualize morphology has yet to be widely applied, perhaps due to its limited specificity. Here, we seek to expand on previous work which combined quantitative phase imaging with a molecularly sensitive Förster resonance energy transfer (FRET) construct by developing additional analysis techniques. This work seeks to characterize the response of individual cells to mechanical stimulus through a novel, to the best of our knowledge, QPI-guided cellular segmentation algorithm. The multimodal imaging instrument and analysis techniques are employed to examine cellular responses to hypo-osmotic stimulus by observing the calcium ion flux using a FRET-based sensor coupled with a mapping of intracellular mass reorganization using QPI. The combined imaging modality enables a discrimination of cell response by localized region, revealing distinct behavior between regions and relative to a control group. Our novel analysis techniques can be used to identify cell expansion and cell region specific responses in both modalities due to the stimulus. With the broad array of FRET sensors under development, the complementary addition of QPI offers new avenues for studying cell responses to a range of environmental stimuli.","PeriodicalId":501620,"journal":{"name":"Journal of the Optical Society of America A","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142181933","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}
