Testing and Implementation of the Generalised Optical Differentiation Wavefront Sensor

Bachelor thesis | Natuurkunde (BSc)

This thesis paper reports on the development of the Generalised Optical DifferentiationWavefront Sensor (g-ODWFS), a newly introduced wavefront sensor that relies on the polarisation of light to measure phase slopes and that may be well suited for applications such as high-contrast imaging. The wavefront sensor has been simulated through a computer model and its (broadband) performance has been analysed on the basis of sensitivity and dynamic range. Furthermore, a g-ODWFS prototype was designed, which has been successfully integrated in a high-speed closed-loop adaptive optics system in the lab.
