The photoacoustic effect (PAE) of weak microsecond pulsed light (WMPL) has immense potential for application to biomedical engineering. However, practical measurements and theoretical analysis the pressure WMPL are lacking. Hence, we constructed a measurement system using an electret piezoelectric sensor multi-wavelength parameter-adjustable generator. Based on system, interacting with air medium induced by different optical parameters was measured. measured data were analyzed fixed variable method, response characteristic obtained. It found that results conform law energy conversion but have specific trend some wavelengths. discussion conducted based classical wave equation PAE, extended presented. is shown proposed approach provides reliable basis pressure.
