ECBO – European Conferences on Biomedical Optics Plenary Session:

Monday, June 26, 2023, 14:00–15:30
Room 5, ICM – International Congress Center Messe München

Title: “Fluorescence lifetime imaging of NAD(P)H and FAD to monitor immune cell metabolism and function”


We demonstrate optical redox ratio and fluorescence lifetime imaging microscopy of intrinsic metabolic co-factors NAD(P)H and FAD to quantify metabolic changes in human immune cells from peripheral blood. This approach is attractive because it does not require cell surface labels or transfection, enabling rapid assessment of single cell metabolism. Newly trained neural networks automatically segment single cells for analysis of heterogeneity within and between patients. Overall, this approach is attractive for both basic research and patient management in cancer and immunology.

Title: “Holotomography and artificial intelligence: label-free 3D imaging, classification, and inference of live cells and organoids”


Holotomography (HT) is a powerful label-free imaging technique that enables high-resolution, three-dimensional quantitative phase imaging (QPI) of live cells and organoids through the use of refractive index (RI) distributions as intrinsic imaging contrast1-3. Similar to X-ray computed tomography, HT acquires multiple two-dimensional holograms of a sample at various illumination angles, from which a 3D RI distribution of the sample is reconstructed by inversely solving the wave equation. By combining label-free and quantitative 3D imaging capabilities of HT with machine learning approaches, there is potential to provide synergistic capabilities in bioimaging and clinical diagnosis. In this presentation, we will discuss the potential benefits and challenges of combining QPI and artificial intelligence (AI) for various aspects of imaging and analysis, including segmentation, classification, and imaging inference3-6. We will also highlight recent advances in this field and provide insights on future research directions. Overall, the combination of QPI and AI holds great promise for advancing biomedical imaging and diagnostics.

Optical Metrology Plenary Session:

Title: “Remote photonic medicine”

Wednesday, June 28, 2023, 10:30–11:25
Room 1, ICM – International Congress Center Messe München


I will present a photonic sensor that can be used for remote sensing of many biomedical parameters simultaneously and continuously. The technology is based upon illuminating a surface with a laser and then using an imaging camera to perform temporal and spatial tracking of secondary speckle patterns in order to have nano metric accurate estimation of the movement of the back reflecting surface. The capability of sensing those movements in nano-metric precision allows connecting the movement with remote bio-sensing and with medical diagnosis capabilities.

The proposed technology was already applied for remote and continuous estimation of vital bio-signs (such as heart beats, respiration, blood pulse pressure and intra ocular pressure), for molecular sensing of chemicals in the blood stream (such as for estimation of alcohol, glucose and lactate concentrations in blood stream, blood coagulation and oximetry) as well as for sensing of hemodynamic characteristics such as blood flow related to brain activity.

The sensor can be used for early diagnosis of diseases such as otitis, melanoma and breast cancer and lately it was tested in large scale clinical trials and provided highly efficient medical diagnosis capabilities for cardiopulmonary diseases. The capability of the sensor was also tested and verified in providing remote high-quality characterization of brain activity.

Digital Optical Technologies Plenary Session:

Title: “End-to-end simulation in propelling the new wave of optics and photonics innovation”

Monday, June 26, 2023, 09:00–10:00
Room 21, ICM – International Congress Center Messe München


Significant advances continue to be made in the design and development of next generation optical and optically enabled products across many industries and applications, from automotive to consumer electronics, healthcare to aerospace and defense, data communications to quantum computing…and much more. These advances are being fueled by innovations in underlying technologies, including scalable manufacturing of complex aspheric and freeform geometries, fabrication of high efficiency micro-optic and diffractive optic components, and the development of photonic devices with directly integrated light engines and sensors. While challenges remain in component-level design, the next set of advancements in optical product development are being driven from a wholistic, integrated approach that incorporates all elements into a system engineering view. Simulation plays a critical role in enabling this system-level view, from the micro- (or nano-) scopic to the macroscopic level. In this talk, I will highlight the role of Multiphysics simulation in the design and development of advanced optical systems, such as optical interconnects, digital lighting, LIDAR sensors, and AR headsets.

Herbert-Walther-Award Presentation:

Title: “Quantum Computation and Quantum Simulation with Strings of Trapped Ca+ Ions”

Tuesday, June 27, 2023, 08:30–10:00
Room 8 "Gustav Hertz" A 12 - Hall A1


The state-of-the-art of the Innsbruck trapped-ion quantum computer is briefly reviewed. We present an overview on the available quantum toolbox and discuss the scalability of the approach. With up to 50 fully controlled ion qubits we perform quantum simulations investigating quantum transport and emerging hydrodynamics features. Employing the quantum toolbox for entanglement-enhanced Ramsey interferometry, we find optimal parameters for quantum metrology. Quantum computers can be protected from noise by encoding the logical quantum information redundantly into multiple qubits using error-correcting codes. Manipulating logical quantum states by imperfect operations requires that all operations on the quantum register obey a fault-tolerant circuit design to avoid spreading uncontrolled errors. We demonstrate a fault-tolerant universal set of gates on two logical qubits in the trapped-ion quantum computer.


Rainer Blatt’s research focuses on trapped ions as a means to address fundamental questions in quantum optics, spectroscopy, and quantum information science. In the laboratory, individual ions are confined in electromagnetic traps under ultrahigh vacuum, and their electronic states are manipulated and probed using laser beams. Experiments in his group, including the demonstration of quantum gates and highly entangled ion strings, have established that ions are outstanding candidates for quantum bits in a quantum computer. Current research themes include the investigation of light-matter quantum interfaces, the scalability of ion traps for quantum information processing, and the use of trapped ions to simulate quantum processes.
