摘要：

Interleaved Rapid-Scan (continuous scan) and time-resolved Step-Scan techniques were modified in order to use these techniques for modulation experiments. The demodulation of the time-resolved spectra was done by software, replacing expensive Lock-In amplifiers. The new techniques lead to the same results compared to conventional Lock-In Step-Scan methods but show dramatically shortened measurement times with respect to the same signal-to-noise ratio.
