LAMBDA

Measurements for biomedical applications Fiber optic and image-based solutions for measurements

Description:
The Lambda Lab (Laboratory of Measurements for Biomedical Applications) is part of the Measurement and Experimental Techniques area. The main research fields of the group are based on fiber optic and image-based measurements for biomedical applications, along with light-based approaches for minimally invasive therapy and monitoring. The Lambda Lab develops innovative and experimental solutions for thermometry in biological tissues undergoing laser and nanoparticles-enhanced photothermal treatments. The team works on novel algorithms for temperature-based therapy control, and in the field of hyperspectral imaging for biomedical applications. A new research line is developed in the field of biomechanical monitoring for health and sport activities.
