bicep2 和凯克阵列是偏振敏感微波望远镜，它们以度角尺度观察来自南极的宇宙微波背景 (CMB)，以寻找 CMB 中印记为 B 模式偏振的膨胀特征。 bicep2 于 2009 年底部署，使用 512 个天线耦合过渡边缘传感器测辐射热计在 150 GHz 下观察了三年，直到 2012 年底，并报告了在度角尺度上检测到 B 模式偏振。 Keck 阵列于 2010 年底首次部署，并将在 2016 年使用五个接收器在多个频率（95、150 和 220 GHz）进行观测。 bicep2 和 Keck 阵列共享共同的光学设计，并采用经过现场验证的 bicep1 策略，即使用小孔径、冷、同轴折射光学器件，在保持大视场的同时提供出色的系统控制。该设计允许使用地面微波源来全面表征远场光学性能。在这里，我们描述了这两种仪器的光学设计，并报告了 150 GHz 下 bicep2 和 Keck 阵列的光学性能和光束的完整特征。
bicep2 and the Keck Array are polarization-sensitive microwave telescopes that observe the cosmic microwave background (CMB) from the South Pole at degree angular scales in search of a signature of inflation imprinted as B-mode polarization in the CMB. bicep2 was deployed in late 2009, observed for three years until the end of 2012 at 150 GHz with 512 antenna-coupled transition edge sensor bolometers, and has reported a detection of B-mode polarization on degree angular scales. The Keck Array was first deployed in late 2010 and will observe through 2016 with five receivers at several frequencies (95, 150, and 220 GHz). bicep2 and the Keck Array share a common optical design and employ the field-proven bicep1 strategy of using small-aperture, cold, on-axis refractive optics, providing excellent control of systematics while maintaining a large field of view. This design allows for full characterization of far-field optical performance using microwave sources on the ground. Here we describe the optical design of both instruments and report a full characterization of the optical performance and beams of bicep2 and the Keck Array at 150 GHz.
