- Pressure sensitivity of an unsteady PSP measurement can be controlled by the differential method.
Demonstration of Differential Luminescent Imaging Method
Acoustic pressure obtained by the differential luminescent imaging. Peak-to-peak acoustic pressure measurement of ±200 Pa using the present method is shown as an example below.
