| Abstract: | The working principle of photoacoustic modulation is described through a theoretical analysis and by the comparison with transmitting grating. A clearer physical picture was obtained for the process of the photo -beating.Therefore students can understand the experiment thoroughly,and their knowledge can be broadened extensively. |
| Keywords: | photo - beat photoacoustic modulation diffraction phase grating |
