Schematic of the mechanism of expanding the Fourier frequency of collecting the spatial distribution of the signals for imaging. (a) Wave vector in the Fourier space of signal collection using an objective lens from a diffraction limited spot, (b) Fourier space augmented by the projected structured line with wave vector (k_s), (c) combined wave vector of the objective and the structured light in one direction, and (d) The combined Fourier space addressed using the microscope.
