We report an experimental method that combines nonlinear-crystal-based transient
detection imaging (TDI) with interferometric complex-field retrieval. The system allows …

We utilize the finite time constant of a photorefractive optical novelty filter microscope to
access full-field velocity information of fluid flows on microscopic scales. In contrast to …

In biological fluid mechanics powerful imaging methods for flow analysis are required for
making progress towards a better understanding of natural phenomena being optimised in …

In this letter we present a technique which employs a photorefractive lithium–niobate crystal
for novelty filtering. Due to the minimal trail formation exhibited by this novelty filter, it can be …

We propose and demonstrate holographic phase contrast (HPC) as a new method to
transfer a spatial phase distribution of arbitrary shape into a corresponding intensity pattern …

We quantitatively investigate the axial imaging properties of dynamic phase-contrast
microscopy, with a special focus on typical combinations of tracer particles and …

A nonlinear dynamic phase-contrast stereoscope has been developed for the measurement
of all three velocity components of a microfluidic flow field. The stereoscope system captures …

In biological fluid mechanics powerful image acquisition systems which guarantee
biocompatibility are required for making progress towards a better understanding of natural …

In live sciences, the observation and analysis of moving living cells, molecular motors or
motion of micro-and nano-objects is a current field of research. At the same time, microfluidic …

In this contribution, we present a photorefractive lithium-niobate novelty Mter microscope.
We derive conditions, based on the photorefractive model by Kukhtarev et al.[1], for …
