Abstract
A light modulation panel is inserted into an optical path of an imaging lens composed of an image-forming optical system to make the imaging lens function as a depth-of-field-extended optical system. The light modulation panel has power that makes a peak position of defocus MTF when the imaging lens is used alone to function as the image-forming optical system and a peak position of defocus MTF when the imaging lens functions as the depth-of-field-extended optical system by insertion of the light modulation panel into the optical path of the imaging lens coincide with each other.
