Re: Invention Time
How would you do that? the AO should present a focused image to the CCD. How would a CCD correct an unfocused image?
In addition the large CCD camera will be just one of a number of instruments that will be attached to the telescope — 4 currently being built plus a fibre-optic feed, more will be developed. The adaptive optics technology on the mirrors means having to do the job just once and hopefully do it well.
The alternative would be to have correction systems on each instrument, some of which might not be suitable to such manipulation.
