The CFHT Adaptive Optics Bonnette : Publications and reports

Some Adaptive Optics Bonnette Related Technical Publications...

• "Estimation of the adaptive optics long-exposure point-spread function using control loop data".
  Compressed (173 kB) version of the article published in JOSA A, 14 (11), 3057-3069, 1997.
  This article gives an extensive description of the method to estimate the PSF related to each image using the wavefront sensor measurements and the commands to the deformable mirror, accumulated in synchronization with the acquisition.

• "Experiences operating CFHT's adaptive optics system".
  Compressed (54 kB) version of the paper presented at the SPIE meeting 3353, held in Kona, Hawaii, in March 98.
  Abstract : The Canada-France-Hawaii Telescope adaptive optics system has now been on the sky for two years. During that time it has been installed on the telescope 13+ times with over 100 nights of scheduled observing time. It is routinely producing red and near infrared images with 0.10 arc second full-width half-max under median seeing conditions. We present the experience we have gained using this system. We discuss installation and set up including characterization, tuning, and focusing. We consider observer training on and following use of the system. And we consider support issues.

• "Performance of the Canada-France-Hawaii Telescope Adaptive Optics Bonnette".
  Compressed (389 kB) version of the article published in PASP, 110, 152-164, 1998.
  This is a very extensive report on the performance of PUEO. It includes a short system description and an analysis of the wavefront and the image characteritics, on bright and faint guide stars. This can be easily used to find out what performance can be expected on a particular object (does not quantify the effect of the guide star spatial extension).

• "Breakthrough in telescope technology unveiled atop Mauna Kea" ,
  was a front page article in the 1996 October 6th edition of the West Hawaii Today.

• "First results of the CFHT Adaptive Optics Bonnette on the telescope" ,
  Compressed (50 kB). Presented at the OSA meeting on "Adaptive Optics", Maui, July 1996.
  Abstract : The CFHT adaptive optics bonnette is a general user instrument for astronomical applications. The results of the first technical and scientific runs at the telescope, not available at the summary due date, will be presented but are obviously not reported in this paper. A brief system description is given. We present the expected system performance and laboratory results.

• "The Canada-France-Hawaii adaptive optics bonnette II: simulations and control" ,
  Compressed (162 kB) version. This paper was presented at the SPIE meeting 2201, held in Kona, Hawaii, on March 94.
  Abstract : We report on the results of the system simulation software written at Canada-France-Hawaii Telescope (CFHT), to predict and optimize the performance of our adaptive optics bonnette presently under construction. The individual simulation elements, atmospheric simulator, curvature sensor, bimorph mirror and control loop, are reviewed with an emphasis on the basic properties of curvature sensors. Optimization of the extra-focal distance parameter and its consequences are discussed. We then present results of whole system simulations, and quantify the main sources of error. Some results, including noise, are reported. In a second part, we present our view of modal control and detail the construction of the modal basis. We also report briefly on modal gain optimization.

• The proceedings of the Workshop on Astronomy with the CFHT Adaptive Optics Bonnette which took place in Quebec in May 1994 is still available. All participants and members of CFHT committees should have received copies. If you wish to receive a copy contact the CFHT librarian (L. Bryson) at bryson@cfht.hawaii.edu.

• "PUEO modal control : Modified Gendron's method" ,
  Compressed (48 kB). Report in which the layout of PUEO's modal control is presented (more precisely mode gain optimization in closed-loop).
