Abstract
An image-forming optical system includes a plurality of image-forming lenses that form a final image and at least one intermediate image; a first phase modulator that is disposed closer to an object side than any one of the intermediate images formed by the image-forming lenses and that applies a spatial disturbance to a wavefront of light coming from the object; and a second phase modulator that is disposed at a position that sandwiches at least one of the intermediate images with the first phase modulator and that cancels out the spatial disturbance applied to the wavefront of the light coming from the object by the first phase modulator.
