Real-time synthetic-aperture digital holographic microscopy

Synthetic aperture digital holographic microscopy extends the resolution and reduces pared to conventional digital holographic microscopy. Typically, this technique involves of holograms with varying illumination angles, followed by a meticulous reconstruction combine the images in the spatial frequency domain. Here we propose a single-capture real-time numerical reconstruction. Furthermore, we employ a modular approach, module and a self-reference capture module can be attached to an existing life-science and straight forward alignment. A mathematical model of image formation enables deconvolution step in the real-time reconstruction process to enhance small features. on a range of biological samples clearly demonstrate the high quality and practical imaging biological samples and the improvement of the method over classical coherent in terms of resolution and noise.
