Atmospheric Turbulence and its Influence on Adaptive Optics
... Adaptive Optics (AO) is still a relatively young branch of astronomical instrumentation. Different technologies are developing all the time and it can be difficult keeping up with all the different acronyms (e.g. GLAO, MOAO, MCAO, SLGS, RLGS, etc..) never mind the technologies themselves. It is easy ...

Diffraction grating has periodic structure that splits and diffracts light
... Ordinary pressed CD and DVD media are every-day examples of diffraction gratings and can be used to demonstrate the effect by reflecting sunlight off them onto a white wall. (see ). This is a side effect of their manufacture, as one surface of a CD has many small pits in the plastic, arranged in a s ...
