Abstract
An apparatus, system, and method for solid state spark detection are disclosed. A semiconducting photodetector has a pair of electrical conductors for carrying an electrical current generated when the semiconducting photodetector receives light energy generated by sparks. An electrical current detector is operably coupled with the electrical conductors for sensing the electrical current generated to signal receipt of the light energy generated by sparks. The present invention can be coupled to a monitoring device, such as an oscilloscope, for monitoring intensity and/or timing of spark phenomena. A plurality of semiconducting photodetectors and associated electrical current detectors may be used in concert if desired. The semiconducting photodetectors are suitably adapted to respond to light energy of different magnitudes or wavelengths to more particularly study sparks of different natures.
