Abstract: A structured illumination microscope includes a holographic image generator that generates a holographic image at a position overlapping an observation object. The structured illumination microscope further includes an image sensor that senses an interference image generated by overlapping the observation object with the holographic image. The structured illumination microscope additionally includes an image recovery processor that recovers an image of the observation object by comparing received data of the holographic image to received data of the interference image.
