About this position
This PhD project at ARCNL focuses on lensless 3D optical imaging, where computational optical imaging is used to recover object structure from diffraction patterns without conventional microscope objectives. The challenge is to move beyond existing 2D lensless approaches and develop high-resolution volumetric imaging methods for complex structures in a compact fiber-based format.
You will work on a combination of optical experiments and algorithm development. On the experimental side, the project involves building and optimizing ptychography setups using visible light, spatial light modulators, and multimode fibers. You will study illumination and detection strategies that increase information content and improve imaging performance.
On the computational side, the research addresses depth-resolved reconstruction from limited measurements. This includes developing algorithms based on compressive sensing, sparsity priors, physics-informed reconstruction, and data-driven machine learning approaches. A key goal is to reconstruct complex optical fields and depth-dependent sample structure from structured speckle illumination.
The project also includes the development of a compact all-fiber 3D imaging demonstrator aimed at semiconductor metrology. You will therefore collaborate with ASML research on wafer metrology while working in ARCNL’s research environment at Amsterdam Science Park. ARCNL carries out fundamental research on the physics and chemistry behind nanolithography, with a strong connection to semiconductor technology.
The position is supervised by Lyuba Amitonova.
