We develop both ultrasonic and optical sources and receivers for measuring surface geometry, position and velocity of solid objects, fluids, gases and suspensions. Research is also performed on measurements of temperature and pressure in fluids as well as concentration and physical properties of the constituents of suspensions. A particular focus is development of SPICE based simulation models for sensors which enables co-design of both sensor and electronics.
Signal processing, including image- and multidimensional signal processing, forms an integral part of our research to enable reliable measurements even under adverse signal/noise conditions.
Examples of current research projects are:
