Characterization of microlenses by digital holographic microscopy

Tristan Colomb, Frédéric Montfort, Etienne Cuche, Christian Depeursinge, Pierre Marquet, Jonas Kühn, Florian Charrière

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 ...

Total aberrations compensation in digital holographic microscopy with a reference conjugated hologram

Tristan Colomb, Christian Depeursinge, Pierre Marquet, Nicolas Aspert, Jonas Kühn, Florian Charrière

In this paper we present a new method to achieve quantitative phase contrast imaging in Digital Holographic Microscopy (DHM) that allows to compensate for phase aberrations and image distortion by recording of a single reference hologram.We demonstrate tha ...

Cell refractive index tomography by digital holographic microscopy

Tristan Colomb, Frédéric Montfort, Etienne Cuche, Christian Depeursinge, Pierre Marquet, Jonas Kühn, Florian Charrière, Mihaela Marian

For what we believe to be the first time, digital holographic microscopy is applied to perform optical diffraction tomography of a pollen grain. Transmission phase images with nanometric axial accuracy are numerically reconstructed from holograms acquired ...
