Abstract:
The present invention provides a detection apparatus for detecting a plurality of marks provided on a substrate, comprising: an optical system; an illumination unit configured to selectively illuminate the plurality of marks with a plurality of light beams via the optical system such that each of the plurality of marks is illuminated with at least one light beam; and an image capturing device configured to capture an image of the plurality of marks via the optical system, wherein the illumination unit includes a change unit configured to individually change an incident angle of each of the plurality of light beams on a pupil plane of the optical system, thereby changing an irradiated position of each of the plurality of light beams on the substrate.

Claim (Index 4):
The apparatus according to  claim 1 , wherein\n the illumination unit includes a diffractive element configured to diffract a light beam emitted by a light source to generate the plurality of light beams, and a lens configured to condense the light beams generated by the diffractive element, and the change unit individually changes the incident angle of each of the plurality of light beams on the pupil plane by changing relative positions of the diffractive element and the lens.
