Abstract

Two methods were developed to compensate for the timing skew of CMOS SPAD line sensors used for time-resolving Raman spectroscopy. Both methods were tested using a time-resolving Raman spectrometer built around a 256-channel CMOS SPAD line sensor. As an example, Raman spectrum of highly fluorescent sesame seed oil was measured. Most of the distortion in the measured spectrum was caused by the timing skew and about 75 % of it could be removed by using either of the methods presented.
