Abstract:
1. A microscope system that performs structured illumination, comprising: a light source configured to emit illumination light; an objective lens that irradiates a specimen with the illumination light; a phase-modulation spatial light modulator that has a two-dimensional pixel structure, that is arranged at a pupil conjugate position of the objective lens on an illumination light path between the light source and the objective lens, and that is configured to modulate a phase of the illumination light for each pixel so as to form a fringe illumination pattern on the specimen based on an optical parameter of at least one of the light source and the objective lens; and an optical deflector unit that is arranged on an illumination light path between the spatial light modulator and the objective lens, and that is configured to move a position on the specimen at which the fringe illumination pattern is formed; wherein the optical parameter includes at least one of a wavelength of the illumination light emitted from the light source, a numerical aperture of the objective lens, and a magnification of the objective lens.
