Q/U成像实验（QUIET）是一个对来自地面的宇宙背景辐射（CMB）偏振进行非常灵敏的测量的实验计划。该项目的一个关键组成部分是生产大量探测器以达到所需灵敏度的能力。利用喷气推进实验室在毫米波封装方面的突破，开发了一种片上偏振计，适用于半导体工业中的大规模生产技术。我们描述了这些旋光模块的设计，实施和性能的安静的第一阶段，并简要讨论了进一步的模块开发计划。
The Q/U Imaging Experiment (QUIET) is an experimental program to make very sensitive measurements of the Cosmic Background Radiation (CMB) polarization from the ground. A key component of this project is the ability to produce large numbers of detectors in order to achieve the required sensitivity. Using a breakthrough in mm-wave packaging at JPL, a polarimeter-on-a-chip has been developed which lends itself to the mass-production techniques used in the semiconductor industry. We describe the design, implementation and performance of these polarimeter modules for QUIET Phase I and briefly discuss the plans for further module development.
