Opto-Spectrum measurement and analysis of underwater plasma acoustic source pulse discharge
Underwater plasma acoustic source (UPAS) with high voltage pulse arc discharge produced pressure wave has the advantage of adjustable pulse length, high source level output, and no pollution to the environment. In recent years, this kind of source has been gradually used in domain as long range target detection, geo-acoustic profile measurement, and frogman threats deposal etc. While for a fairly long time, were lack of research on the company product of sound—light. In this paper, we measured the optospectrum of UPAS by experiment, and found its spectrum is of continuous spectrum and its dominant energy is around 500nm, if we raise the discharge voltage, reduce the gap distance of the tips, the spectrum amplitude and half peak amplitude width will increase, and if we change steel tips with copper tips, the light energy distribution and amplitude of the spectrum will change.
