|Title:||Quantitative phase-gradient imaging at high resolution with asymmetric illumination-based differential phase contrast||Authors:||Mehta, S.B.
|Issue Date:||1-Jul-2009||Citation:||Mehta, S.B., Sheppard, C.J.R. (2009-07-01). Quantitative phase-gradient imaging at high resolution with asymmetric illumination-based differential phase contrast. Optics Letters 34 (13) : 1924-1926. ScholarBank@NUS Repository. https://doi.org/10.1364/OL.34.001924||Abstract:||We describe a full-field phase-gradient imaging method: asymmetric illumination-based differential phase contrast (AIDPC). Imaging properties of AIDPC are evaluated using the phase-gradient transfer-function approach and elucidated with experimental images of an optical fiber and a histochemical preparation of a skeletal muscle section. In comparison with full-field differential interference contrast, AIDPC does not require phase shifting for quantitative imaging of phase gradient, provides artifact-free images of birefringent specimens, requires shorter camera exposure, and has larger depth of focus. It is amenable to transferfunction engineering, simultaneous fluorescence imaging, and automated live cell imaging. © 2009 Optical Society of America.||Source Title:||Optics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/67249||ISSN:||01469592||DOI:||10.1364/OL.34.001924|
