Figure 4: Characterization of the stimulated Raman projection microscope.
From: Volumetric chemical imaging by stimulated Raman projection microscopy and tomography
(a) The measured stimulated Raman projection (SRP) signal from PDMS films as a function of the sample thickness. The red line is the linear fitting curve for the measured data points (R2=0.9977). (b,c) The SRP signal of PDMS as a function of the Stokes power (b) and the pump power (c). The red lines are the linear fitting curves for the measured data points (R2=0.9980 for the Stokes power and R2=0.9998 for the pump power). (d) The SRP noise as a function of the pump power. The red curve is the fitting result of the measured data points (R2=0.9931). (e) The signal-to-noise-ratio (SNR) of the SRP microscopy as a function of sample concentration. The red line is the linear fitting curve of the measured data points (R2=0.9994). (f) The SRP spectrum of DMSO in D2O at a concentration of 21.84 mM.
