Optical design and laboratory characterisation of CAWS: the Calibration and Alignment Wavefront Sensor for high-order adaptive optics Open
The Calibration and Alignment Wavefront Sensor (CAWS) is a common-path interferometer for high-order adaptive optics (AO).With a resolution comparable to that of a 51-by-51 sub-apertures Shack-Hartmann sensor (SHS), it can directly measure…

Experience with wavefront sensor and deformable mirror interfaces for wide-field adaptive optics systems Open
Recent advances in adaptive optics (AO) have led to the implementation of wide field-of-view AO systems. A number of wide-field AO systems are also planned for the forthcoming Extremely Large Telescopes. Such systems have multiple wavefron…
