Extended Data Fig. 7: Illumination grating periods and modulation depth of 4Pi-SIMFLUX.
From: 4Pi-SIMFLUX: 4Pi single-molecule localization microscopy with structured illumination
a,b, The cross-correlation spectrum of the 0th and +1st order components in the x- or y-direction. The white dots within the red circles indicate the wavevector’s magnitude and orientation of the structured illumination, corresponding to the illumination grating periods of 210 nm (x-direction) and 209 nm (y-direction), respectively. c,d, Experimental modulation depths estimated from single molecules in the dataset shown in Fig. 3a are 0.91 and 0.92 in the x- or y-direction, respectively.
