In order to analyze the light of cosmic objects, particularly at
extremely great distances, spectroscopy is the workhorse of astronomy.
In the era of very large telescopes, long-term investigations are mainly
performed with small professional instruments. Today they can be done
using self-designed spectrographs and highly efficient CCD cameras,
without the need for large financial investments.
This book explains the basic principles of spectroscopy, including the
fundamental optical constraints and all mathematical aspects needed to
understand the working principles in detail. It covers the complete
theoretical and practical design of standard and Echelle spectrographs.
Readers are guided through all necessary calculations, enabling them to
engage in spectrograph design. The book also examines data acquisition
with CCD cameras and fiber optics, as well as the constraints of
specific data reduction and possible sources of error. In closing it
briefly highlights some main aspects of the research on massive stars
and spectropolarimetry as an extension of spectroscopy. The book offers
a comprehensive introduction to spectroscopy for students of physics and
astronomy, as well as a valuable resource for amateur astronomers
interested in learning the principles of spectroscopy and spectrograph
design.
