| Abstract: | In this paper, an apparatus used for pulsed solid photoacoustic experiment is described. Experimental results for solid film of potassim per-manguate and leaf of glossy privet show that the piezoelectric transducer made by ourselves has high sensitivity. The signal amplitude is gre.iter than l00mv. Based on the experimental results, the optimum conditions for pulsed photoacoustic excition and the method of photoacoustic study for biomedical samples are analysed. |
