In January, Miriam Menzel visited the optics group to work on an experiment to measure scattering patterns in monkey and human brain tissue using coherent Fourier scatterometry. By transmitting a non-focused laser beam through unstained histological brain sections, the scattering patterns for small tissue regions (with diameters of 0.1–1 mm) were obtained. These patterns show accordance with the simulated scattering patterns. In this way we showed that is possible to reveal individual fiber orientations for up to three crossing nerve fiber bundles, with crossing angles down to 25°.

A unique Soft X-Ray source was recently installed at the Optics Research Group of the department of Imaging Physics. This source will play a key role within the LINX-consortium, which TU Delft leads. The aim of this consortium is to generate new techniques to image extremely small features in 3D, for example on next generation computer chips.

Konstantine Cheishvili joned ImPhys per August 1, 2020. He will be working on the project NanoRheoOCT. His supervisor is Jeroen Kalkman.

Siamak Abolhassani joined ImPhys per July 16th, 2020. During his PhD, he is going to address the well-known cycle skipping problem in conventional FWI through hybridizing Joint Migration Inversion (JMI) and FWI techniques under the supervision of Dr. Eric Verschuur.

Dr. Iman Esmael Zadeh, postdoc in the Optics Group, has been invited by Prof. Harry Awater of Caltech to give a talk on Wednesday 5 August in the ACS Photonics Global Webinar about his recent paper.

Iman Zadeh (1st author), Jin Chang (PhD student), Jereon Swens (bachelor student), Yuri Staaden (stagiaire) and Silvania Pereira in collaboration with KTH (Sweden), Tianjin University (China) and Single Quantum have published an article on the development and applications of very efficient single photon detectors with 7.7. ps time resolution.

On August 3rd, 2020 the new online course “Pre-university Physics” will start. The instructors Jeroen Kalkman, Liedewij Laan, Sander Otte and Timon Idema will guide prospective students into the academic approach of physics. The course consists of three modules: mechanics, electricity & magnetism, and waves.

Read about Sebastian Weingärtner, one of the 'Rising Stars' of the Delft Health Initiative. Weingärtner is setting up his own lab at ImPhys. He will focus on MRI physics. For his research at TU Delft, he already got his first grant approved, the NWO start-up grant, which aims to support labs in the basic sciences.

On July 17th, 2020 Boling Ouyang successfully defended his PhD thesis on "Integrated photonics interrogator and sensors for ultrasound detection".

It is common knowledge in optics that, when only tar fields are measured, there is a fundamental limit to the resolution given by the wavelength of the light. Yet research continues to beat this fundamental limit.
