Photographic acoustic
WebOPO-based photoacoustic spectroscopy (PAS) provides ultimately fast and sensitive trace gas analysis. The photoacoustic infrared spectroscopy (PAS) is a very promising technology for trace gas detection and analysis in environmental or atmospheric monitoring, industrial process control or medical diagnostics. PAS is based on exciting rotational ... WebThe principal of the photoacoustic effect is simple. Nanosecond pulsed laser light is used to illuminate the tissue. Chromophores such as hemoglobin and red blood cells absorb the light which causes local heating and thermoelastic expansion. Pressure or sound waves are emitted and detected by our ultra high frequency transducers.
