The far-infrared imager and polarimeter (FIP) for the Origins Space Telescope (Origins) is a basic far-infrared imager and polarimeter. The camera will deliver continuum images and polarization measurements at 50 and 250 μm. Currently available detector technologies provide sufficient sensitivity for background limited observations from space, at least on a single pixel basis. FIP incorporates large next-generation superconducting detector arrays and our technology development plan will push the pixel numbers for the arrays to the required size of 8000. Two superconducting detector technologies are currently candidates for the instrument: transition edge sensors or microwave kinetic inductance devices. Using these detectors and taking advantage of the cryogenic telescope that is provided by Origins, FIP will achieve mapping speeds of up to eight orders of magnitude faster than what has been achieved by existing observatories. The science drivers for FIP include observations of solar system objects, dust properties, and magnetic field studies of the nearby interstellar medium, and large scale galaxy surveys to better constrain the star formation history of the universe to address one of the main themes of Origins: “How does the Universe work?” In addition to the science, the FIP instrument plays a critical functional role in aligning the mirrors during on orbit observatory commissioning.

起源太空望远镜的远红外成像仪和旋光仪

Origins太空望远镜（Origins）的远红外成像仪和旋光仪（FIP）是基本的远红外成像仪和旋光仪。摄像机将以50和250μm的分辨率提供连续图像和偏振测量。当前可用的检测器技术至少在单个像素的基础上为从太空进行的背景受限观察提供了足够的灵敏度。FIP集成了大型的下一代超导检测器阵列，我们的技术开发计划会将阵列的像素数推向所需的8000个尺寸。目前，该仪器可采用两种超导检测器技术：过渡边缘传感器或微波动电感器件。使用这些探测器并利用Origins提供的低温望远镜，FIP将比现有天文台实现高达8个数量级的映射速度。FIP的科学驱动力包括对太阳系物体，尘埃特性的观测以及对附近星际介质的磁场研究，以及大规模星系测量，以更好地限制宇宙的恒星形成历史，从而解决起源的主要主题之一： “宇宙如何运作？” 除了科学以外，FIP仪器在轨道观测站调试过程中的对准镜子方面也起着至关重要的作用。大规模星系调查，以更好地限制宇宙的恒星形成历史，以解决起源的主要主题之一：“宇宙是如何工作的？” 除了科学以外，FIP仪器在轨道观测站调试过程中的对准镜子方面也起着至关重要的作用。大规模星系调查，以更好地限制宇宙的恒星形成历史，以解决起源的主要主题之一：“宇宙是如何工作的？” 除了科学以外，FIP仪器在轨道观测站调试过程中的对准镜子方面也起着至关重要的作用。
