LED based photoacoustic NO $_{2}$ sensor with sub-ppb detection limit

Juho Karhu, Tuomas Hieta, Farshid Manoocheri +2

A high-sensitivity LED based photoacoustic NO $_{2}$ sensor is demonstrated. Sensitive photoacoustic gas sensors based on incoherent light sources are typically limited by background…

Optical power detector with broad spectral coverage, high detectivity and large dynamic range

Jussi Rossi, Juho Uotila, Sucheta Sharma +6

Optical power measurements are needed in practically all technologies based on light. Here we report a general-purpose optical power detector based on the photoacoustic effect. Opt…
