Movies of cellular and sub-cellular motion by digital holographic microscopy

open access: yesBioMedical Engineering OnLine, 2006
Background Many biological specimens, such as living cells and their intracellular components, often exhibit very little amplitude contrast, making it difficult for conventional bright field microscopes to distinguish them from their surroundings.

Digital Holography Display (2)

open access: yesPhysics Procedia, 2011
AbstractThis paper describes the extension work from the last Digital Holography Projector System. From the developed works shows that, some unforeseen factors have created the difficulties for the system alignment. Such factors are the DMD frame rate, light source and diffractive zero order.
