Applications of digital holographic microscopes with partially spatial coherence sources

Abstract

We implemented partially spatial coherent illuminations in digital holographic microscopes (DHM) working in transmission. The benefits gained with those sources are outlined. A major advantage is the drastic reduction of the speckle noise making it possible high image quality comparable to the best classical transmission microscopes. Several implementations of biomedical applications, where digital holography provides significant information, are described. With a rapid DHM permitting the analysis of dynamical phenomena, applications in microfluidics are also provided. © 2008 IOP Publishing Ltd.
