Lasers in astronomical spectroscopy-1

Optics Technology, 1970
Abstract In contrast to most other methods of spectroscopy, where electronics is becoming increasingly important at the recording end of the measurement process, it is possible to construct a spectrographic device using electronics also directly on the receiving side.

Trends in Astronomical Spectroscopy

1975
A brief survey is made of improvements in spectroscopic data analysis in recent years. The need for accurate observational material is stressed, especially with the highly efficient receivers now available. A few problems that will be studied for many years are considered: stellar evolution and nucleogenesis, stellar atmospheres and chromospheres ...

Infrared Astronomical Spectroscopy

1978
Spectroscopic instruments are designed to divide radiation into its component wavelengths (or frequencies) and to provide the observer with a display of this information at high signal-to-noise ratio (SNR).

Introduction to Spectroscopy and Astronomical Observations

2018
This chapter presents an introduction to the techniques and tools used in astronomy and astrophysics research, mainly focused on spectroscopy. The basic concepts of spectroscopy are first described, from the Schrodinger equation to the Lambert–Beer’s law.

Self-scanned digicon: a digital image tube for astronomical spectroscopy.

Applied Optics, 1975
We have successfully fabricated, tested, and operated a digital image tube consisting of a magnetically focused image intensifier tube in which a self-scanned linear array of 1024 silicon photodiodes operating in the EBS mode serves as the photoelectron ...

Updating a handbook on astronomical spectroscopy

Journal for the History of Astronomy, 2015
This is the second, updated edition of a book that first appeared in 1986 and was critically reviewed in this journal (February 1988) by Joann Eisberg. Consequently, I will focus my remarks on the new or substantially changed parts. As Hearnshaw himself reveals in the preface to the new edition (p.
