高威利物浦成像偏振仪(GLIP)被设计成以亚秒的节奏同时进行线偏振和圆偏振测量。该仪器的科学目标是利用领先的机器人望远镜设施对快速演变的天文瞬变进行观测。GLIP建立在由利物浦天体物理研究所的利物浦望远镜团队开发的Ringo&Moptop系列偏振仪和爱尔兰国立大学戈尔韦(NUIG)开发的GAP偏振仪的基础上。该仪器作为一个2.3弧分视野的四光束成像偏振器工作在一个探测器上，一旦知道仪器的特征矩阵，就可以确定整个图像场中的完整斯托克斯矢量[I，Q，U，V]。将讨论光学设计、偏振特性以及利用计算、实验室测试结果和数学方法对仪器光学元件的公差。
The Galway Liverpool imaging polarimeter (GLIP) has been designed to perform simultaneous linear and circular polarimetric measurements at sub-second cadence. The science goal of the instrument is to perform observations of fast evolving astronomical transients with leading robotic telescope facilities. GLIP builds on the legacy of polarimeter instruments developed by the Liverpool Telescope team of the Astrophysical Research Institute, Liverpool, with the RINGO & MOPTOP series, and the National University of Ireland Galway (NUIG) with the GASP polarimeter. The instrument works as a four-beam imaging polarimeter of a 2.3 arc-minute field-of-view onto one detector, allowing the determination of the full Stokes vector [I Q U V] across the image field once the characteristic matrix of the instrument is known. Optical design, characterisation of polarimetry and tolerance of the instrument optical components using computational, lab testing result & mathematical methods will be discussed.
