Abstract

To determine a position of an object (100) parallel to the optical axis (120) of an optical device (1), the object (100) is illumined from a first illumination direction (210-1) and from a second illumination direction (210-2) and an image (230-1, 230-2) is acquired in each case. The position of the object (100) is determined based on a distance (250) between imaging locations of the object (220-1, 220-2) in the images (230-1, 230-2).
