论文摘要
对于天文仪器，对光学指向和耦合的准确了解对于在集成和部署之前表征（子）系统的一致性和性能至关重要。理想情况下，这需要光学系统的相位响应，该光学系统对于直接（相不敏感的）检测器以前无法访问。在这里，我们使用双光源杂质杂质技术在350 GHz处的大型视野微波动力学探测器摄像头展示了相敏感的复合束图案技术的开发。我们在这里显示您如何使用傅立叶光学器件分析测量的数据，该数据允许在望远镜部署之前集成到望远镜模型中，以计算ON Sky Beam模式和望远镜孔径效率。
For astronomical instruments, accurate knowledge of the optical pointing and coupling are essential to characterize the alignment and performance of (sub-)systems prior to integration and deployment. Ideally, this requires the phase response of the optical system, which for direct (phase insensitive) detectors was not previously accessible. Here we show development of the phase sensitive complex beam pattern technique using a dual optical source heterodyne technique for a large field of view Microwave Kinetic Inductance Detector camera at 350 GHz. We show here how you can analyze the measured data with Fourier optics, which allows integration into a telescope model to calculate the on sky beam pattern and telescope aperture efficiency prior to deployment at a telescope.
