The Visible Spectro-Polarimeter (ViSP) is one of the first light instruments for the Advanced Technology Solar Telescope (ATST). It is an echelle spectrograph designed to measure three different regions of the solar spectrum in three separate focal planes simultaneously between 380 and 900 nm. It will use the polarimetric capabilities of the ATST to measure the full Stokes parameters across the line profiles. By measuring the polarization in magnetically sensitive spectral lines the magnetic field vector as a function of height in the solar atmosphere can be obtained, along with the associated variation of the thermodynamic properties. The ViSP will have a spatial resolution of 0.04 arcsec over a 2 arcmin field of view (at 600 nm). The minimum spectral resolving power for all the focal planes is 180,000. The spectrograph supports up to 4 diffraction gratings and is fully automated to allow for rapid reconfiguration.
Solar Spectropolarimetry of Ca II $8542~Å$ Line: Polarimeter Development,Calibration and Preliminary Observations
色球磁场对于了解太阳大气中高能事件的动力学具有极其重要的意义。在科代卡纳尔太阳观测站,过去研制了几台偏振计,用于研究活动区的磁场。一台新的偏振计已经研制完成并安装在Kodaikanal塔-隧道望远镜上,用于研究Ca II $8542~Å$谱线中色球水平的活动区。仪器和旋光策略的设计方面进行了讨论。望远镜仪器的偏振已经被重新审视,并提出了减少偏振的可能方法。本文讨论了Zemax提出的用来检验分析仪器偏振模型的望远镜偏振模型。简要介绍了旋光仪控制单元和旋光仪操作软件。文中介绍了仪器的偏振定标、观测结果、仪器偏振改正和样品斯托克斯剖面。极化精度和灵敏度分别优于$3\times10^{-2}$和$3\times 10^{-3}$。

Imaging Spectropolarimeter for Multi-application Solar Telescope at Udaipur Solar Observatory: Characterization of polarimeter and preliminary observations
多用途太阳望远镜(Multi-Application Solar Telescope,MAST)是一台离轴50厘米的格里高利望远镜,最近在乌代布尔太阳天文台(Udaipur Solar Observatory,USO)开始运行。为了了解太阳磁场和速度场的演变和动态,正在研制一种成像分光偏振计,作为多天线空间望远镜的后端仪器之一。该系统由窄带滤光片和偏振计组成。偏振计包括一个线性偏振器和两组液晶可变延迟器(LCVR)。该仪器用于同时观测617.3 nm和854.2 nm的谱线,这两条谱线分别形成于光球层和色球层。在本文中,我们提出的结果,从表征的LCVR的谱线的利益和响应矩阵的偏振计。我们还提出了初步的观察使用分光偏振仪获得的活动区域。为了验证,我们比较了Stokes观测的活动区太阳动力学天文台(SDO)上的日震磁成像仪(HMI)和MAST观测的谱线617.3 nm。考虑到MAST观测的有限性,我们发现两个观测之间有很好的一致性。
