Test system for a Shack-Hartmann sensor based telescope alignment demonstrated at the 40cm Wendelstein Telescope

摘要

A commercial Shack-Hartman wavefront sensor is being used in a test setup installed at the Wendelstein 40 cmtelescope to test methods for telescope alignment based on reverse optimization. Measured low-order Zernikewave-fronts are being used to determine the misalignment of the telescopes optical elements. Then a procedureto 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 acquisitioncamera.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
