A.1.1.5 Charged coupled device
Use of CCD to capture images. Structure and operation of the charge coupled device: A CCD is silicon chip divided into picture elements (pixels). Incident photons cause electrons to be released. The number of electrons liberated is proportional to the intensity of the light. These electrons are trapped in "potential wells" in the CCD. An electron pattern is built up which is identical to the image formed on the CCD. When exposure is complete, the charge is processed to give an image. Quantum efficiency of pixel > 70%.
A.1.2 Non-optical Telescopes
Single dish radio telescopes, I-R, U-V and X-ray telescopes. Similarities and differences compared to optical telescopes including structure, positioning and use, including comparisons of resolving and collecting powers.

I have downloaded ALL your Astrophysics resources to improve my own knowledge of the subject before I teach it. Thank you for making them available for sharing. They must represent hours of work. I may use some when I deliver the topic also, as long as you don't mind...?
