Nonlinearity and image persistence of P-20 phosphor-based intensified photodiode array detectors used in CARS spectroscopy

摘要: Several self-scanning photodiode arrays (IPDA) used for CARS spectroscopy are shown to exhibit a greater image persistence than has generally been realized, and falloff in sensitivity that is logarithmic with decreasing output signal. These effects attributed the P-20 phosphor based intensifiers IPDAs probably generic all such detectors. A strategy minimizing presented. prototype detector incorporating much faster rare earth evaluated be more suited single pulse measurements turbulent combustion phosphors.
