Abstract
An optical apparatus includes an image sensor, which outputs a signal responsively to an optical image formed on the image sensor. Objective optics focus optical radiation from an object so as to form the optical image on the image sensor, while superimposing a characteristic structure on the optical image. A processor processes the signal so as to generate an electronic image of the object while detecting, responsively to the characteristic structure, a deviation in an alignment of the objective optics relative to the image sensor.
