A New Type of Atmospheric Dispersion Corrector Suitable for Wide-Field High-Resolution Imaging and Spectroscopy on Large Telescopes

Autor: Andrew Rakich

Publikováno v: Applied Sciences, Vol 11, Iss 14, p 6261 (2021)

Atmospheric dispersion produces spectral elongation in images formed by land-based astronomical telescopes, and this elongation increases as the telescope points away from the zenith. Atmospheric Dispersion Correctors (ADCs) produce compensating disp

The impact of Roland Shack's wavefront sensor on the development of modern active optics

Autor: Andrew Rakich

Publikováno v: Roland V. Shack Memorial Session: A Celebration of One of the Great Teachers of Optical Aberration Theory.

This paper discusses the impact that Roland Shack and his eponymous wavefront sensor have had on the development of active optics in astronomy. There are a number of interesting threads to this story, from the early concept development and its driver
