多通道减法双通（MSDP）是一种成像光谱技术，它允许在具有高空间和时间分辨率的2D视场上观察谱线轮廓。自1977年以来，它一直被广泛用于各种光谱仪（Meudon，Pic du Midi，德国真空塔望远镜，THEMIS，Wrocketaw）。我们总结了以前的发展，并描述了一个新的设计，已在Meudon开发的能力，具有更高的光谱分辨率和增加的通道数：光谱采样与切片器的太阳能仪器（S4I），它可以结合一个新的和快速的偏振分析。这种新一代MSDP技术非常适合大型望远镜。还介绍了一个衍生的紧凑版本的仪器，太阳能谱线发射多普勒仪（SLED），致力于动态研究的日冕循环中观察到的禁止的铁线，和双折射的目标。它是为观测日全食而设计的，并可分别用于观测日珥和日冕的弗罗茨瓦夫和隆姆尼奇峰日冕仪。
The Multichannel Subtractive Double Pass (MSDP) is an imaging spectroscopy technique, which allows observations of spectral line profiles over a 2D field of view with high spatial and temporal resolution. It has been intensively used since 1977 on various spectrographs (Meudon, Pic du Midi, the German Vacuum Tower Telescope, THEMIS, Wrocław). We summarize previous developments and describe the capabilities of a new design that has been developed at Meudon and that has higher spectral resolution and increased channel number: Spectral Sampling with Slicer for Solar Instrumentation (S4I), which can be combined with a new and fast polarimetry analysis. This new generation MSDP technique is well adapted to large telescopes. Also presented are the goals of a derived compact version of the instrument, the Solar Line Emission Dopplerometer (SLED), dedicated to dynamic studies of coronal loops observed in the forbidden iron lines, and prominences. It is designed for observing total solar eclipses, and for deployment on the Wrocław and Lomnicky peak coronagraphs respectively for prominence and coronal observations.
