Method and device for compensating geometrical distortion errors in optical imaging systems

摘要

In order to correct geometrical distortions in an optical imaging system, a deformable mirror (2) is inserted between the object plane (O) and the aperture stop (EP), whose surface inclination can be varied locally by a multiplicity of actuators (23) that can be operated independently of one another. The distortion correction is intended, in particular, for optoelectronic imaging systems, in order to correct distortions which are produced in the optoelectronic interfaces (image-converter tubes, monitors). <IMAGE>
