Proposed optical setup. (a) Temporal illumination spectrum. The minimum and maximum wavelengths, λmin = 580 nm and λmax = 597 nm are defined by the 1/e2 bandwidth around the peak wavelength, λc = 588 nm. (b) Light illumination unit composed of two DMDs. (c) Diffractive modulation based on off-axis scheme. The black arrows denote the sample conjugated planes with corresponding magnification factors. The denoted focal lengths of the lenses are in millimeters. The definitions of the abbreviations are as follows: SS, supercontinuum source; BPF, band-pass filter; BS, beam splitter; trans., translation stage; cond., condenser lens; obj., objective lens; and pol., polarizer.
