The optical telescope is the symbol of astronomy, the collector of radiation from astrophysical sources. The telescopes and their aberrations will be firstly discussed using the formalism of geometric optics. The present telescopes use reflecting optical elements, generally two mirrors, in different configurations to reduce the aberrations.

Contemporary Physics, 2015
Since Galileo’s first observations in 1609, telescopes have grown dramatically in size. Larger telescopes collect more light, allowing astronomers to detect fainter sources and to look further back in time towards the birth of the universe. The angular resolution of these telescopes, however, has been limited by turbulence in the earth’s atmosphere ...

Astronomy With Adaptive Optics
Adaptive Optics, 1995The operation of the ESO ComeOn adaptive optics system, under its successive improved versions at La Silla on the 3.6 m telescope since 1991, has produced a great number of new scientific results. In addition, it has started a learning process for an efficient use of adaptive optics in diffraction-limited imaging from the ground with large telescopes ...

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.

Abstract The purpose of this chapter is to provide an overall perspective on the application of adaptive optics to ground-based astronomy. It addresses questions such as: What is the function of adaptive optics? How does it improve astronomical observations? What effect does it have on the design of telescopes and instrumentation? How is
