A User-oriented Comparison of the Techniques for 3D Spectroscopy
Abstract
A comparison of the most popular techniques for 3D spectroscopy is presented in a way which should hopefully be useful for astronomers intending to use these techniques. Integral field spectroscopy, slitless spectroscopy, tunable imaging filters, imaging Fourier transform spectroscopy, and energy-resolving detectors are included in their different implementation. Their relative advantages and disadvantages are discussed in view of the possible scientific application.
