标题： A User-oriented Comparison of the Techniques for 3D Spectroscopy

摘要： 本文以一种希望能对打算使用这些技术的天文学家有用的呈现方式，对三维光谱学中最流行的技术进行了比较。其中包括了积分场光谱学、无狭缝光谱学、可调滤光片、成像傅里叶变换光谱学以及能量分辨探测器，并对其各自的实现形式进行了介绍。从可能的科学应用的角度讨论了它们的相对优缺点。 显示英文摘要

摘要： 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.
