For functional testing of optical systems, typically Shack-Hartmann-based sensors consisting of a combination of a micro lens matrix and a CCD/CMOS sensor are utilized. Their lateral resolution is restricted to the size of the micro-lenses, and the maximum measurable wavefront slope is usually significantly limited to avoid ambiguous signals on the detector. Here, we present a similar measurement method which is, however, based on a digital micro-mirror matrix for selecting subapertures in reflection. This leads to enhanced measurement capabilities in functional testing of optics. |
