天体物理学远红外探测任务（PRIMA）将在其光谱仪模块中使用8千像素的动能电感探测器（KID）阵列。我们提出了一种改进的谐振频率到空间位置的映射系统，旨在将阵列从映射装置转移至飞行舱后仍能保留其映射关系。该映射是天文观测所必需的，还允许我们对KID的电容元件进行激光修整，以优化频率空间中的谐振间距。这通过消除碰撞谐振提高了工作良率，减少了串扰，并降低了随时间变化的频率漂移敏感性。
英文摘要
The Probe far-Infrared Mission for Astrophysics (PRIMA) will use 8 kilo-pixel kinetic inductance detector (KID) arrays in its spectrometer module. We present an improved resonant frequency to spatial position mapping system designed to preserve each array's mapping after transferring it from the mapping apparatus to the flight housing. Such a mapping is necessary for astronomical observations, and additionally allows us to laser trim the capacitive elements of KIDs to optimize resonance separation in frequency space. This increases the operating yield by eliminating collided resonances, reduces crosstalk, and reduces the sensitivity to frequency drift over time.
