Our most recent work is out on OCT flowmetry in organ-on-chip (OoC) devices, see rdcu.be/eytR3. In this work we took on the challenge of measuring very small flow speeds in a OoC device using particle-image velocimetry and number-fluctuation OCT.

Six interdisciplinary research projects on optical broadband systems receive funding | NWO
Optical broadband systems play an important role in various sectors, from health diagnostics to the agri-food sector. In order to (further) develop these technologies, the Future Optical Broadband Systems research programme was launched within the Knowledge and Innovation Covenant. With this funding, six consortia can start interdisciplinary research into semiconductor chips, hyperspectral imaging and tomography imaging, amongst others.

These two scientists not only shared a Nobel prize, but are also buried at the same cemetery, which happens to be right around the corner from my home. Gravestones of Lorentz and Zeeman at Kleverlaan cemetery Haarlem.

Recently published work by our group showed the application of dual-wavelength digital holography for industrial metrology.
We used two wavelengths in a lensless digital holography system to extend the depth range to 50 micrometer.

Our latest work is out on wavenumber dependent dynamic light scattering optical coherence tomography
doi.org/10.1364/OE.521702
What did we do? We improved DLS-OCT to measure particle size for dense colloidal suspensions where particle ordering plays a role in particle diffusion.
