Paper Abstract

A commercial Shack-Hartman wavefront sensor is being used in a test setup installed at the Wendelstein 40 cm telescope to test methods for telescope alignment based on reverse optimization. Measured low-order Zernike wave-fronts are being used to determine the misalignment of the telescopes optical elements. Then a procedure to optimize wave-front performance by aligning the telescope secondary mirror is applied. The setup contains a collimating optical system, the Shack-Hartman sensor and a guiding and acquisition camera.
