Abstract

In certain applications, modal wavefront sensors (MWFSs) can outperform zonal
wavefront sensors, which are widely used due to their high flexibility. In this paper, a
holography-based MWFS as described is developed for the fast position control of a light
emitter in a deep parabolic mirror. The light source is located in the vicinity of the focal
point. Instead of Zernike polynomials, more complex phase functions, which are related to
certain dislocations of the light source are used as detector modes. The performance of
the sensor is verified with a test setup, where the test wavefront is generated by a spatial
light modulator instead of a real parabolic mirror. The design and fabrication of the required
high-resolution holographic element is described and an easy way of multiplexing several
single mode sensors is demonstrated.
