Comparative phase imaging of live cells by digital holographic microscopy and transport of intensity equation methods. [PDF]
Opt Express, 2020 We describe a microscopic setup implementing phase imaging by digital holographic microscopy (DHM) and transport of intensity equation (TIE) methods, which allows the results of both measurements to be quantitatively compared for either live cell or ...

Three dimensional tracking of gold nanoparticles using digital holographic microscopy [PDF]
Novel Biophotonic Techniques and Applications, Munich : Germany
(2011), 2011 In this paper we present a digital holographic microscope to track gold colloids in three dimensions. We report observations of 100nm gold particles in motion in water. The expected signal and the chosen method of reconstruction are described.

Digital Holographic Microscopy [PDF]
Imaging and Applied Optics 2016, 2011 Microscopy is one of the main research and application areas of digital holography. Direct access to the phase as well as amplitude profiles makes quantitative phase microscopy by digital holography (DH-QPM) particularly powerful and versatile. A number of techniques of DH are developed especially for microscopy imaging and these are made possible ...

Label-Free Analysis of Urine Samples with In-Flow Digital Holographic Microscopy. [PDF]
Biosensors (Basel), 2023 Urinary tract infections are among the most frequent infectious diseases and require screening a great amount of urine samples from patients. However, a high percentage of samples result as negative after urine culture plate tests (CPTs), demanding a ...

Digital holographic microscopy of spiropyran‐based dynamic materials
Journal of Microscopy, 2023 Spiropyran (SP)‐based dynamic materials undergo structural changes in response to external stimuli. In this paper, we show that digital holographic microscopy (DHM) is an effective candidate for characterisation of SPs (embedded in polymer matrices) and ...
