Abstract

In this paper, the Atacama Submillimeter Telescope Experiment (ASTE) is presented. A 10-m aperture telescope hosts a camera equipped with a transition edge sensor (TES). We developed a fore-optics module-"APol," to convert the 271 pixels of the TES working at 350 GHz into a sensitive imaging polarimeter without sacrificing the image quality and the ${7.5}^\prime$7.5 field of view. Here, we describe the detailed optical design of APol and present the results of the preliminary test in a laboratory.

摘要

本文介绍了阿塔卡马亚毫米波望远镜实验（ASTE）。一台10米口径的望远镜搭载了一台配备过渡边缘传感器（TES）的相机。我们开发了一个前置光学模块——“APol”，在不牺牲图像质量和7.5角分视场的情况下，将工作在350吉赫兹的271像素TES转换为一个灵敏的成像偏振计。在此，我们描述了APol的详细光学设计，并展示了在实验室进行的初步测试结果。
