摘要 |
<p>A light irradiation apparatus includes a light modulation element which has a phase modulation area having at least one basic pattern for modulating a light beam, an illumination system which illuminates the phase modulation area of the light modulation element with a light beam, and an image formation optical system which causes a light beam on an irradiation target surface a light intensity distribution having an inverse-peak-shaped pattern formed based on the light beam phase-modulated by the phase modulation element to fall on an irradiation target object. Dimensions of the basic pattern are not greater than a point spread function range of the image formation optical system converted in terms of the light modulation element. The phase modulation area is configured in such a manner that a phase distribution in a light complex amplitude distribution on the irradiation target surface becomes a saw-tooth-like distribution along a line segment in a lateral direction.</p> |
