Subjects: Sensors, Test and MeasurementSpeaker: Markku Vainio (University of Helsinki)
Chairman: Hans-Peter Loock (, Queen's University Kingston)
We have combined a cantilever-enhanced photo-acoustic trace gas sensor with a passive optical power build-up cavity, resulting in a 100 times sensitivity enhancement and an unprecedented NNEA of 1.75×10^-12 Wcm^-1Hz^-1/2.
