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.

Imaging device for imaging at least one object

An interferometer for optically measuring an object (), including a light source (), at least one beam splitter () and at least one detector (), with the beam splitter being arranged in the beam path of the light source such that a light beam created by the light source is split into a working beam () and a reference beam (). The interferometer is embodied such that the working beam impinges on the object () to be measured and the working beam is at least partially reflected by the object and interfered with the reference beam on the detector (). Here it is essential that the interferometer is provided with a spatial light modulator, which comprises a hologram control unit () and a hologram reconstruction unit () connected thereto, with the hologram reconstruction unit being arranged in the beam path of the working beam between the beam splitter () and the object () and the hologram control unit () controlling the hologram reconstruction unit () such that the hologram reconstruction unit creates an optionally predetermined hologram such that the working beam is deflected and/or split by the hologram reconstruction unit.
