The CFHT Adaptive Optics Bonnette : Publications and reports

Some Adaptive Optics Bonnette Related Publications...

• "Performance of the Canada-France-Hawaii Telescope Adaptive Optics Bonnette".
  Version submitted to PASP. Compressed (386 kB) or uncompressed (1156 kB). This is a very extensive report on the performance of PUEO. It includes a short system description (as below) 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 (72kB) or uncompressed (718 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 (212kB) or uncompressed (670 kB) versions. 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 now available. All participants and members of CFHT committees should have received copies. If you wish to receive a copy contact the librarian (L. Bryson) at bryson@cfht.hawaii.edu.

• "PUEO modal control : Modified Gendron's method" ,
  Compressed (64kB) or uncompressed (242 kB). Report in which the layout of PUEO's modal control is presented (more precisely mode gain optimization in closed-loop).
