摘要：

This paper compares and contrasts two signal processing schemes, viz. the fast filter and the gated integrator. It is shown that the use of a gated integrator further increases the SNR advantage over CW excitation, and extends the use of pulsed excitation to allow the recording of Raman spectra samples at significantly higher temperatures. The use of a ratioing circuit to correct for laser pulse-to-pulse energy fluctuations is also demonstrated.
