Shack-Hartmann (SH) sensors are used in a growing number of optical wavefront applications, however the conventional design of these sensors limits their dynamic range, and consequently they produce false results if the curvature of the measured wave-front is too large. To overcome this dynamic-rang...

Phase-shifting interferometers are optical phase sensors that can be used to measure fast, transient phenomena. However their commercial use has been limited due to their relatively high costs and the speed limitations on what these devices can measure. Conventional MEMS-based interferometers are co...
