In December, a new research project is introduced daily on the Twitter account of Academy Programmes (#AKA_RADDESS). One of the videos will present our UNIDET project, in which we develop a new universal approach for optical power detection. Our detector is based on the photoacoustic effect. It provides about 8 orders of magnitude of linear dynamic range (from nW-level to W-level) in electromagnetic power detection, covering all wavelengths from UV to far infrared! Extension to THz will follow!
Introduction to the "Radiation Detectors for Health, Safety and Security (RADDESS)" programme of the Academy of Finland.
