Abstract
An imaging device and method for imaging an object, such as for multispectral or hyperspectral imaging, are disclosed. The imaging device includes an image sensor located in an image plane of the imaging device. The image sensor includes photosensitive elements. A first imaging system is configured to generate an intermediate image of the object in an intermediate image plane. A second imaging system is configured to generate an image of the intermediate image on the image sensor in the image plane. A diffractive optical element is arranged in the intermediate image plane. An aperture is arranged in a beam path of the second imaging system between the intermediate image plane and the image sensor. The diffractive optical element, the second imaging system, and the aperture are arranged such that different images for different wavelengths of the intermediate image are generated on different groups of the photosensitive elements.
