IMAGING DEVICE FOR MULTISPECTRAL OR HYPERSPECTRAL IMAGING AN OBJECT

An imaging device (110) and a method for imaging at least one object (112), specifically for multispectral imaging or hyperspectral imaging, are disclosed. The imaging device (110) comprisesI. at least one image sensor (114) located in at least one image plane (116) of the imaging device (110), the image sensor (114) comprising a plurality of photosensitive elements (118);II. at least one first imaging system (120) configured for generating at least one intermediate image (122) of the object (112) in at least one intermediate image plane (124);III. at least one second imaging system (132) configured for generating at least one image (134) of the intermediate image (122) on the image sensor (114) in the image plane (116);IV. at least one diffractive optical element (142) arranged in the intermediate image plane (124); andV. at least one aperture (144) arranged in a beam path (146) of the second imaging system (132) between the intermediate image plane (124) and the image sensor (114),wherein the diffractive optical element (142), the second imaging system (132) and the aperture (144) are arranged such that at least two different images for at least two different wavelengths of the intermediate image (122) are generated on at least two different groups of the photosensitive elements (118).
