Abstract:
1. An imaging apparatus comprising: a diffraction grating which diffracts electromagnetic waves from an electromagnetic wave source; a shield grating which shields a part of the electromagnetic waves diffracted by the diffraction grating; a detector which detects an intensity distribution of the electromagnetic waves through the shield grating; and an adjusting unit which adjusts an attitude of at least one of the diffraction grating and the shield grating on the basis of the detection result by the detector, wherein the adjusting unit: obtains information on the intensity distribution detected by the detector; and adjusts an inclination of at least one of the diffraction grating and the shield grating so as to reduce a variation in distance between the diffraction grating and the shield grating such that the intensity distribution detected by the detector is maintained within an imaging range.
