Detection of Light

Vak 2014-2015

Description

Detectors are the crucial link between the astronomical target and the observer. Apart from the telescope, their performance is arguably the most important component – and often weakest link – in the chain of observational devices. As astronomers are aiming at fainter and fainter targets, the quality and calibration of the detector systems have become increasingly important.
Topics to be covered include intrinsic and extrinsic photo-conductors, CCDs, infrared arrays, photodiodes, bolometers, coherent receivers, and submillimeter- and millimeterwave heterodyne receivers. In addition, this course covers practical aspects which are of general interest to the observer, such as cosmetic quality, linearity and dynamical range, spectral response and bandwidth, and quantum efficiency and noise.

Course objectives

The main objectives of this course are to provide an overview of:

  • the various technologies (and underlying physics) used to detect UV to the sub-millimeter radiation;
  • the most common devices to be found at an observatory;
  • performance aspects and artifacts of detectors;
  • readout and calibration strategies for detectors.
