On the Spectral Quality of Time-Resolved CMOS SPAD-Based Raman Spectroscopy with High Fluorescence Backgrounds

This data is related to the article “On the Spectral Quality of Time-Resolved CMOS SPAD-Based Raman Spectroscopy with High Fluorescence Backgrounds” that have been submitted to the IEEE Sensors Journal. The folder named “Fluorescence_to_Raman_ratio_(post-it_notes)” contains the data that was collected in the measurements where the effects of fluorescence-to-Raman ratio on the spectral quality were studied. Please, see the measurement procedures and results from the article under sections III. B and IV. A, respectively. The folder named “Recording_time_and_excitation_intensity_(oils)” contains the data that was collected in the measurement where the effects of the recording time and excitation intensity on the spectral quality was studied. Please, see the measurement procedures and results from the article under sections III. C and IV. B, respectively.

The measurement data is stored to the text files named as “Data.txt”. The datafiles have 8 columns and 256 rows. The columns represent the 8 time bins of the sensor and the rows in the datafiles represent the 256 spectral columns in the line sensor. The numbers in the cells of the datafiles represent the photon counts at a specific time bin and spectral column, i.e. at a specific wavenumber. The text files named as “Wavenumber_axis.txt” under the two main data folders contains the wavenumber values for each of the spectral columns in the sensor for the different measurements. The folders named as “DCR_corresction_data.txt” contains the dark count correction data for the different measurements.
