Workshop "Trends and Developments in Laser Based Distance Metrology"
This workshop will first address the latest state-of-the-art approaches to laser-based distance, followed by in-depth topics on instrumental and environmental limitations, with the overall goal to lay a foundation for pushing this limits to the next level. It will take place at the Lorentz Center@Oort in Leiden. Dr. Nandini Bhattacharya is one of the four organizers.

Ulas Taskin joined our group as PhD
Ulas Taskin, who is from Turkey, joined our group as PhD on 1 February. He did his MSc in Istanbul Technical University working on ‘Inverse Scattering Problem of Microwave Imaging’. He started his PhD project on ‘Full-Waveform Acoustic Inversion for Breast Cancer Detection’. He will work on developing inversion methods and test them with synthetic data first, and experimental data later on. His supervisor is Koen W.A. van Dongen.

QI: Aloys Erkelens started his MSc project
Aloys started his MSc thesis on: "Developing an effective characterization method of ring-resonator ultrasound sensors without the need of packaging" on November 14th. In more detail, this includes mounting of fibres to grating couplers, design and fabrication of a watertight mounting method of the photonic sensor and measurements with the sensor.” His supervisors are Boling Ouyang and Jaap Caro.

OP: PhD Zheng Zhu for 4 years with a CSC scholarship
Zheng Zhu is a PhD for 4 years, with a CSC scholarship and we will be working ons his project on "the absolute length metrology". His supervisors are: Prof. Paul Urbach and Dr. Nandini Bhattacharya.
From light spots to supersharp images
Making detailed 3D images of proteins in living cells with a special light microscope, without damaging those cells. That is what Sjoerd Stallinga, winner of an ERC Advanced grant worth 2.3 million euros, wants to achieve. In order to do so he is going to scan samples nanometer by nanometer using a sophisticated 3D light pattern in an approach that requires extensive collaboration between different disciplines.
Spotlight on aggressive cancer cells
Metastases in cancer are often caused by a few abnormal cells. These behave more aggressively than the other cancer cells in a tumour. Miao-Ping Chien and Daan Brinks are working together, from two different universities, on a method to detect these cells. Their research has now been published in Nature Biomedical Engineering
How to find structurally different molecules before they disappear in the average?
Particle fusion for single molecule localization microscopy improves signal-to-noise ratio and overcomes underlabeling, but ignores structural heterogeneity or conformational variability. This study presents a-priori knowledge-free unsupervised classification of structurally different particles employing the Bhattacharya cost function as dissimilarity metric.
The impact of noise on Structured Illumination Microscopy image reconstructions
Super-resolution structured illumination microscopy (SIM) has become a widely used method for biological imaging. Standard reconstruction algorithms, however, are prone to generate noise-specific artifacts that limit their applicability for lower signal-to-noise data. Here we present a physically realistic noise model that explains the structured noise artifact, which we then use to motivate new complementary reconstruction approaches.
A new tool to understand the brain
How does our brain work? An international team of researchers, including lead author Daan Brinks of TU Delft, has taken another step towards answering that question. They have created a new tool that allows them to image electrical signals in brains with an unprecedented combination of precision, resolution, sensitivity, and depth.
Researchers make 3D image with light microscope
For the first time, Delft researchers have succeeded in making a three-dimensional image of a cellular component using light. The component in question is the nuclear pore complex: tunnels that facilitate traffic to and from the cell nucleus. Studying cell components in 3D can help to determine the cause of various diseases, among other things. The researchers have published their findings in Nature Communications.
Decoding movement intentions in the brain using ultrasound waves
While many techniques can image brain activity, this was the first time that a new technology, called functional ultrasound imaging, was used to detect motor planning deep within the brain. The team is now applying functional ultrasound decoding to more complicated motor control tasks. At ImPhys, Dr. Maresca is developing ultrasound technologies to image brain activity down to the cellular scale.
