Claim:
1. An optical imaging system using incoherent structured illumination, comprising: an optical microscope, comprising: an objective having a first side facing a sample, a second side opposite to the first side, a front focal plane, and a back focal plane, wherein the front focal plane superimposes the sample; a stage placed at the first side of the objective, configured to be moved in a direction toward or away from the objective and to accommodate the sample at the surface of the stage facing the objective; a 50/50 beam splitter placed on the optical path to reflect the incident light beams on the second side of the objective and to transmit scattered light from the sample to an imaging recording device; a coherent light source emitting coherent light which forms an optical path passing through the objective; a spatial light modulator positioned on the optical path and configured to generate a structured pattern from the at the front focal plane of the objective, the spatial light modulator diffracting the coherent light into a plurality of beams with different orders; a plurality of optical lenses disposed on the optical path, wherein at least one conjugate image plane of the structured pattern is formed on the optical path by the optical lenses; and a rotating diffuser configured to destroy the coherence of the coherent light, disposed at a plane where the plurality of beams with different orders intersect.
