Jm. Beckers, INTERPRETATION OF OUT-OF-FOCUS STAR IMAGES IN TERMS OF WAVE-FRONT CURVATURE, Journal of the Optical Society of America. A, Optics, image science,and vision., 11(1), 1994, pp. 425-427
The wave-front-curvature-sensing method used by E Roddier for the Univ
ersity of Hawaii's curvature-adaptive-optics system is derived from th
e interpretation in 1979 of the out-of-focus images obtained by use of
the Multiple Mirror Telescope, I summarize those original Multiple Mi
rror Telescope observations and the simple interpretation given in ter
ms of wave-front curvature by use of geometrical optics at that time.
