摘要:

The results of acoustic and photoacoustic testing of an uncoupled Helmholtz resonator suggest its utilization as an open photoacoustic cell. Although signal levels are lower in our cell than in small closed cells, this type of resonator produces very low coherent noise if light scattering by the sample is negligible. The resonator is free of static pressure fluctuation problems as well.
