Characterization of microlenses by digital holographic microscopy [PDF]
Applied Optics, 2006 We demonstrate the use of digital holographic microscopy (DHM) as a metrological tool in micro-optics testing. Measurement principles are compared with those performed with Twyman-Green, Mach-Zehnder, and white-light interferometers. Measurements performed on refractive microlenses with reflection DHM are compared with measurements performed with ...

Digital Holographic Microscopy of Phase Separation in Multicomponent Lipid Membranes [PDF]
, 2016 Lateral in-homogeneities in lipid compositions cause microdomains formation and change in the physical properties of biological membranes. With the presence of cholesterol and mixed species of lipids, phospholipid membranes segregate into lateral domains

Tip Crack Imaging on Transparent Materials by Digital Holographic Microscopy. [PDF]
J Imaging, 2019 With this study, we propose a method to image the tip crack on transparent materials by using digital holographic microscopy. More specifically, an optical system based on Mach−Zehnder interference along with an inverted microscopy (Olympus CKX53 ...

Dynamic Speckle Illumination Digital Holographic Microscopy by Doubly Scattered System
Photonics, 2021 The coherent noise always exists in digital holographic microscopy due to the laser source, degrading the image quality. A method of speckle suppression using the dynamic speckle illumination, produced by double-moving diffusers, is presented in digital ...

Lensfree super-resolution holographic microscopy using wetting films on a chip. [PDF]
, 2011 We investigate the use of wetting films to significantly improve the imaging performance of lensfree pixel super-resolution on-chip microscopy, achieving < 1 µm spatial resolution over a large imaging area of ~24 mm(2).

Digital Holographic Microscopy
Microscopy and Microanalysis, 1999 Abstract We applied phase-shifting digital holography to microscopy in this paper. At first lensless microscopy is proposed, in which no optical adjustment is necessary. Then, the method is applied to relax the limitation of focal depth in traditional optical microscopy.

Holographic microscopy reconstruction in both object and image half spaces with undistorted 3D grid [PDF]
, 2015 We propose an holographic microscopy reconstruction method, which propagates the hologram, in the object half space, in the vicinity of the object. The calibration yields reconstructions with an undistorted reconstruction grid i.e.

Diabetes screening by telecentric digital holographic microscopy [PDF]
Journal of Microscopy, 2015 SummaryDiabetes is currently the world's fastest growing chronic disease and it is caused by deficient production of insulin by the endocrine pancreas or by abnormal insulin action in peripheral tissues. This results in persistent hyperglycaemia that over time may produce chronic diabetic complications.

Linearity and Optimum-Sampling in Photon-Counting Digital Holographic Microscopy
Photonics, 2022 In the image plane configurations frequently used in digital holographic microscopy (DHM) systems, interference patterns are captured by a photo-sensitive array detector located at the image plane of an input object.
