Autor: Rossi, Jussi, Uotila, Juho, Sharma, Sucheta, Hieta, Tuomas, Laurila, Toni, Teissier, Roland, Baranov, Alexei, Ikonen, Erkki, Vainio, Markku

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. Optical power incident on the detector's black absorber produces an acous

Electromagnetic Radiation Detection with Broad Spectral Sensitivity and Large Dynamic Range using Cantilever-based Photoacoustic Effect

Autor: Sharma, Sucheta, Laurila, Toni, Rossi, Jussi, Uotila, Juho, Vainio, Markku, Manoocheri, Farshid, Ikonen, Erkki

A sensitive photoacoustic detection approach employing a silicon cantilever is investigated for power measurement of electromagnetic radiation. The technique which is actuated by pressure waves generated through radiation-induced heat, depicts high s

Report

Photoacoustic characteristics of carbon-based infrared absorbers

Autor: Rossi, Jussi, Uotila, Juho, Sharma, Sucheta, Laurila, Toni, Teissier, Roland, Baranov, Alexei, Ikonen, Erkki, Vainio, Markku

We present an experimental comparison of photoacoustic responsivities of common highly absorbing carbon-based materials. The comparison was carried out with parameters relevant for photoacoustic power detectors and Fourier-transform infrared (FTIR) s
