Abstract
Acoustic resonances are observed in high-pressure discharge lamps operated with ac input modulated power frequencies in the kHz range. This paper describes an optical resonance detection method for HID lamps using computer controlled cameras and image processing software. Experimental results showing acoustic resonances in HPS and metal halide lamps are presented.
