Or perhaps amphibia? Well, it looks like the VLTI depends on collecting photons emitted a long time ago at a place far away, at various points and by means of optical delay lines, combining the collected photons with the proper motion and phasing to enhance the image and get rid of the effects of the earth's turbulent atmosphere. I don't see any need to stick a slit into the VLTI unless you want to run the collected photons through a prism or diffraction grating, in order to determine red/blue shift of a distant object. Perhaps you could explain your breathtaking puzzlement. -- bz please pardon my infinite ignorance, the set-of-things-I-do-not-know is an infinite set. bz+sp(a)ch100-5.chem.lsu.edu remove ch100-5 to avoid spam trap

Perhaps they [wave/photon/wavicle/quantum of goo] have been close friends since birth, a few billion years ago. They were born at almost the same time in almost the same place and have been traveling together for a LONG LONG time. They managed to get separated by a few dozen meters [it was really a silly argument, and they are sorry now that they separated]. If we can manage to get them back together, under the right circumstances, their differences will vanish and magic things will happen. Imagine the image taking form as thousands of long separated photons are focused on the CCD. Breath-taking, isn't it? The trick is in reassembly the groups of the photons, so that the focus of the group is sharp. If they are not delayed by the right amounts, we will be putting together photons that came from entirely different places. Why the emission sources may have been miles apart or even more. That would definitly mess up the focus. The reason we would be putting together the wrong photons is that, as the earth turns, the telescopes ALL need to look at the SAME target. They need to keep photons from that target falling upon the same point on the CCD. If the delays are wrong, you will not accomplish this. Satisfied, Sue? -- bz please pardon my infinite ignorance, the set-of-things-I-do-not-know is an infinite set. bz+sp(a)ch100-5.chem.lsu.edu remove ch100-5 to avoid spam trap

Ahhemm.... I count four mirrors I count four delay lines I count one *indivisible* photon emitted. I count zero instances of the term quarter photon in your reply. Ya practicing for a career in politics ? ;-) Sue... |
