[0017] combine figure 1 The schematic diagram of the optical path of the system further explains the integrated field of view unit system with high spectral resolution based on variable diameter core fiber:
[0018] In the overall design process of the variable diameter core fiber IFU, it is necessary to study the fiber selection, microlens selection, fiber arrangement and fixing mode selection, and system integration mode selection.
[0019] figure 1 Among them, 1 is the focal plane of the telescope, 2 is the front-end optical lens group, 3 is the microlens array, 4 is the variable diameter core fiber array (the entrance end is the large core diameter, the exit end is the small core diameter), and 5 is the slit end ( are pseudo-slits).
[0020] figure 1 , we regard the focal plane 1 of the telescope as the object to be measured, and its image is imaged on the front surface of the microlens array 3 through the front optical lens group 2, and then converged by the microlens ...
