Method and device for analysing the imaging behavior of an optical imaging element

An apparatus for examining the imaging behavior of first imaging optics, said apparatus comprising:

• second imaging optics by which an object is imaged into an image plane and which differs from the first imaging optics in at least one imaging characteristic;
• a spatially resolving detector with pixels, by which detector light in the image plane is detected in the pixels;
• a memory module, in which values for intensity, as a first characteristic of the light, and for at least one further, second characteristic of the light are stored in a spatially resolved manner in the pixels;
• and
• an emulation module, in which the stored values are processed and an emulation image is generated, which emulates an image of an object generated by the first imaging optics, taking into consideration the imaging characteristic and the influence of the second characteristic on the imaging behavior,
• wherein the apparatus generates a series of images by
• dividing a range of values of the second characteristic into partial ranges,
• assigning an image to each partial range, and
• assigning to the pixels of each image the corresponding stored intensity value, if the second characteristic's value assigned to the pixel falls within the partial range assigned to the respective image, and otherwise assigning to said pixels a predetermined intensity value,
• further wherein the emulation module converts the series of images into a series of intermediate images, the emulation including a constant value of the second characteristic for each of the intermediate images, which value of the second characteristic originates from the respective partial range and differs from the values of the second characteristic for the respective other intermediate images, and
• the emulation module combines the intermediate images to form the emulation image.
