Moreover, the pixel-limited spatial resolution was improved by using expanding wave illumination to enable diffraction-limted resolution at 4 micrometer.
What did we do? We extended the height measurements range in digital holography using two wavelengths with very small wavelength separation. This extended the measurement range from half a wavelength to a full millimeter; more than a 30000-fold improvement compared to the single wavelength case!
Our latest work on “Lensless single-shot dual-wavelength digital holography with sub-pixel resolution and centimeter depth range“ is published in APL photonics

Presenting an overview of our work on OCT at the European Machine Vision Forum in Fürth.
Being active with updating and making group software accessible. Now everything on OCT useful Jupyter notebooks with more to come on ODT and holography.

Today, September 2nd, Peter Speets defends his PhD thesis entitled: 'Optical interferometric multi-parameter flow sensing of particle suspensions with complex refractive index models'.
Our group is present at #EOSAM2025 conference in Delft with an invited and poster presentation.
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.
Looking back to a great meeting of the Medical Delta CARES consortium working on sustainable healthcare.

Visiting the SFB Tomography across scales conference in Strobl. Great presentations in a relaxing environment.
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.
Being in a PhD defence is particularly fun when you are on topic and when the quality of the work is good. Great work from Johannes Kuebler.
Presenting our work on '3D computational resolution enhancement in OCT' at the Dutch center for nanolithography research ARCNL
Also, for some reason they did not fly AMS-SFO last Friday (while there is big conference). Had to fly via Frankfurt.
And off we go to @spie.org Photonics West sharing our latest results in dynamic light scattering OCT.
We are joining the great annual Dutch physics conference. With tomorrow a focus session on Dynamic light scattering on soft and living matter.
Today January 20th at 17:30 hrs, Kote Cheishvili will defend his doctoral thesis: "Advancements in dynamic light scattering optical coherence tomography particle sizing and flowmetry " @Delft University of Technology. Check out his thesis: https://buff.ly/42cqsxc
🎇 Wishing Kote great success!
Good feeling to see a new PhD thesis from the group printed and on my desk. Defence follows soon.
New year resolution achieved, the divorce is final, @KaLKMaNLaB on X no longer exists.
ImPhys post-doc Vahid Khandan successfully defended his PhD thesis at Groningen University. Congratulations 🎉
Why are project proposal templates always in Word and never in the scientists preferred Latex format? Fighting with Word the entire morning just to finish in time before the deadline 🎉😬💪🏻
My department is now on Bluesky 🎉🥳🍻 Please follow it on @imphys-tudelft.bsky.social
As long as the career evaluation judges scientific leadership on being last author it can be critical for PDs, asst. prof. striving for an academic career path. It can be a good division between the one who gets in the money (PI) and the one who does the PhD daily supervision (PD, asst. prof.).
I am excited to share that our paper that has just been published in Nature Communications! We show non-invasive real-time 3D dynamic OCT imaging of pathogen development in plants, their growth rates, and quantify plant pathogen resistance.
