Abstract

The paper describes experimental results of photoacoustic pulse stimulation of a Helmholtz resonator in which influence of pulse duty factor on the signal amplitude was studied. The signal was measured by means of a dedicated microprocessor system capable of recording the signal shape and frequency response of the cell. Relationship between the light pulse duty factor and signal in the photoacoustic Helmholtz cell at different frequencies is presented.
