    Abstract: A flashlamp control system is provided with a capacitor that is statically electrically connected to the high voltage power supply, and a current sensing component is then electrically connected to the static capacitor and digital control electronics to monitor the charge current and/or the discharge current to static capacitor. A dynamically switchable capacitor electrically may also be connected to the high voltage power supply and digital control electronics for isolating the dynamically switchable capacitor from the high voltage power supply based on the monitored charge current and/or discharge current. One or more homogenizing element, comprise of an air gap, diffusing homogenizing element, imaging element, non-imaging element or light pipe homogenizing element, may be disposed in the light path proximate to the flashlamp, such as a multichannel distributor if present, to decrease the coefficient of variation of the optical signal, either temporally and spectrally, or both.

    Abstract: Emitted light from a pulsed plasma system is detected, amplified and digitized over a plurality of pulse modulation cycles to produce a digitized signal over the plurality of RF modulation periods, each of which contains an amount of random intensity variations. The individual signal periods are then mathematically combined to produce a stable local reference waveform signal that has decreased random intensity variations. One mechanism for creating a stable local reference waveform signal is by subdividing each of the individual signal periods into a plurality of subunits and the mathematically averaging the respective subunits within the modulation period to produce the stable local reference waveform signal for the modulation period. The stable local reference waveform signal can then be compared to other instantaneous waveform signals from the pulsed plasma system, or waveform parameters can be derived using various signal processing techniques such as Fourier analysis.
