我们研制了远红外干涉望远镜（FITE）的传感器光学系统。FITE的空间分辨率预计为2.5角秒。为了重建图像，需要精确测量干涉的可见性。为此，我们设计了FITE的焦平面。焦平面是传感器光学器件的入射焦点。它的相机光学系统具有用于干涉仪的每个光束的F/106光束。点扩散函数主要由衍射决定，其大小近似对应于阵列的大小，从而可以通过薄片中的阵列测量条纹图案。传感器光学系统由两个红外探测器和光学CCD组成。每个探测器都安装在传感器光学器件的最终焦平面上。远红外探测器的格式为15像素，间距为1.5 mm。中红外探测器和光学CCD被开发作为传感器的干涉仪对准。传感器光学器件和探测器安装在低温恒温器上。由于它们具有足够的规格，我们相信可以达到2.5角秒的空间分辨率。
We developed the sensor optics of the Far Infrared Interferometric Telescope (FITE). The spatial resolution of FITE is expected to be 2.5 arcseconds. In order to reconstruct images, precise measurements of the visibility of the interference are necessary. For this purpose, we designed the focal plane of FITE. The focal plane is the entrance focus of the sensor optics. Its camera optics has the F/106 beam for each beam of the interferometer. The PSF is dominated by diffraction, and its size corresponds approximately to the array size so that the fringe pattern can be measured by the array in the sheet. The sensor optics consists of two infrared detectors and the optical CCD. Each detector is installed on the final focal plane of the sensor optics. The far-infrared detector has the format of 15 pixels with 1.5 mm pitch. The mid-infrared detector and the optical CCD are developed as the sensor for the interferometer alignment. The sensor optics and the detectors are installed on the cryostat. Because of their sufficient specifications, we believe to achieve the 2.5 arcsecond spatial resolution.
