Paper Abstract

The paper analyzes and researches the possibility and measure of photoelectric-inspect of sound frequency by phase modulating. Analyzing the 4-Frame Phase Shifting analyzing method used in sound frequency photoelectric-inspect. It is verified that vibrator film and the position of exploring instrument determines inspecting precision. This step directly influences sound frequency spectrum and dynamic range. A kind of vibrator film choosing reference gist has been brought up. This inspecting method can be used in sound information analyzing.
