Witryna10 gru 2011 · Images are broken by the lens at the front of the eye and projected smaller onto the retina. The nerve endings present there transmit the images (read: prickles) further to the brain and there the prickles are converted into images: the pigeon sees. If we assess the eye we can’t ignore the fact that a small pupil is important. WitrynaThe non-circular shape of the Keck telescopes primary mirror, combined with the fact that the telescope is on an alt/az mount with the adaptive optics system on the left Nasmyth platform, means that as the telescope tracks a star field the hexagonal pupil image rotates on the wavefront sensor camera and on the deformable mirror. This creates a …
