(a) Schematic diagram of a new-generation RFP insertion into a large positioner hole with partial coverage. The two colors (blue and orange) represent the conflict areas. The outer circle represents the pre-existing range of motion of the RFP. (b) This figure presents the optimized result of using new-generation RFPs to replace the original RFPs for full coverage (for a clearer view, only seven RFPs are shown).
