Patent ID: 8649002

Claim:
An imaging system comprising: a stage on where a sample to be observed is arranged; an optical system that forms an image of light irradiated onto the sample in a predetermined focal plane; an imaging element that includes a pixel array in which a plurality of pixels are arranged in a two-dimensional matrix, each of the pixels detecting at least a part of the light of the image of the sample formed in the focal plane, the imaging element obtaining the image of the sample corresponding to the light detected by the pixel array; a spectrum detecting unit that is arranged such as to be adjacent to the pixel array, the spectrum detecting unit detecting a spectrum of the light in the focal plane to output spectrum information; and a correcting unit that corrects the image of the sample obtained by the imaging element based on the spectrum information output from the spectrum detecting unit, wherein the stage moves in a direction perpendicular to an optical axis of the optical system that the light irradiated to the sample is incident to, the spectrum detecting unit comprises a first spectrum detector and a second spectrum detector arranged at positions that are symmetrical to a first direction that is parallel or orthogonal to a row direction or a column direction of the pixel array, taking a predetermined position in the pixel array as a reference, the first spectrum detector detects the spectrum of the light in a first observation region of the sample corresponding to a first region in the focal plane, and outputs first spectrum information, the second spectrum detector detects the spectrum of the light in a second observation region of the sample corresponding to a second region in the focal plane, and outputs second spectrum information, and if there is at least a partial overlap between the first observation region, which corresponds to the first region detected by the first spectrum detector when the stage is at a first position, and the second observation region, which corresponds to the second region detected by the second spectrum detector when the stage is at a second position, the correcting unit corrects the image of the sample obtained by the imaging element based on the first spectrum information, which has been obtained when the first spectrum detector has detected the spectrum of the light of an overlapping observation region, and the second spectrum information, which has been obtained when the second spectrum detector has detected the spectrum of the light of the overlapping observation region.
