Caption

Schematic of the spatial frequency loss in large spatial-frequency-shift microscopy without tunability. (a) Detected spatial frequency range when the spatial frequency of the illumination (denoted as 2feva.) is larger than two folds of the cutoff frequency of the objective. (b) Reconstructed images in large-spatial-frequency-shift condition with the missing band. feva.: the spatial frequency of illumination. NA: numerical aperture of obejctive. SFS: spatial-frequency-shift.
