The group of Kalkman is focused on developing novel optical tomography instrumentation to look inside objects. We focus on a broad range of application areas where optical tomography plays a key role, e.g. life sciences, cultural heritage, and process control. Our focus is on imaging in 3D with optimal imaging performance in terms resolution, speed, and volume. We also focus on quantification of sample parameters from the imaged objects and the development of sensors based on these physical parameters.
Our instrumentation development tools are numerical imaging system simulation, optical design, and laboratory experimental validation in the KaLKMaNLaB. We keep a close eye on potential applications with various industrial and research partners.
