Optical Astronomy: Detectors

  • Rosa PoggianiEmail author
Part of the UNITEXT for Physics book series (UNITEXTPH)


This chapter discusses the instruments used to detect the radiation collected by the optical telescopes and transform it into an electrical signal. The main classes of detectors for optical radiation will be presented. All detectors have a fundamental limit caused by the statistical properties of the electromagnetic radiation. The charge-coupled devices (CCDs) that are the most used detectors at telescopes are discussed in detail.
