synthetic aperture digital holographic Microscopy
, 2014 Digital holographic microscopy (DHM) was developed and. Synthetic aperture is formed by moving the CCD camera to 9 positions and stitched together to increase the field of view with 22 Kilo pixels.We reconstructed the transparent

Automatic multifocusing in digital holographic microscopy
Optics ExpressHolography captures the full three-dimensional optical field of a sample in a single intensity measurement. This enables numerical refocusing to arbitrary axial planes and, in principle, automatic multifocusing in digital holographic microscopy (DHM). Existing work on holographic autofocusing, however, largely targets the simpler single-plane setting ...

Holographic fluorescence microscopy with incoherent digital holographic adaptive optics
Journal of Biomedical Optics, 2015 Introduction of adaptive optics technology into astronomy and ophthalmology has made great contributions in these fields, allowing one to recover images blurred by atmospheric turbulence or aberrations of the eye. Similar adaptive optics improvement in microscopic imaging is also of interest to researchers using various techniques.

Phase Retrieval for Digital Holographic Microscopy With Defocused Holograms
IEEE Photonics Journal, 2018 A new phase retrieval technique in digital holographic microscopy (DHM) with three defocused holograms is proposed. Given the defocusing distance, the phase distributions of tested specimen can be reconstructed with a simple algebraic equation.

Special Issue on Digital Holographic 3D Imaging: Capture, Display, and Evaluation
ETRI Journal, 2019 Holography has been fascinating people for almost 70 years (since Gabor's invention in 1947) as a true three‐dimensional (3D) imaging technology that can replicate 3D scenes in free space.

Microsphere-assisted quantitative phase microscopy: a review
Light: Advanced ManufacturingLight microscopes are the most widely used devices in life and material sciences that allow the study of the interaction of light with matter at a resolution better than that of the naked eye. Conventional microscopes translate the spatial differences in
