Präzision und Sensorspezifikationen der wellenfrontbasierten Justage kleinaperturiger optischer Systeme

Besides the demanding specifications in the manufacturing of single optical components, the complexity of multi-element systems is strongly increased due to positioning aspects of several elements to each other. This positioning requires to be highly precise in order to ensure the best optical functionality possible. Active alignment methods provide an elegant approach to this challenge, since they rely only on the optical function itself to deviate suitable correction actions for the system. This paper discusses an advanced wavefront based alignment algorithm applied to a simple demonstrator system. The results shown, illustrate the achievable precision and grant important insights to the required properties of real wave front sensors, in order to achieve these alignment results in practical applications
