宽视场红外巡天望远镜（WFIRST）将回答有关暗能量随时间演化的基本问题，并将已知系外行星的目录扩展到参数空间的新区域。使用哈勃大小的镜子和18个新开发的HgCdTe 4K x 4K光电二极管阵列（H4 RG-10），WFIRST将测量数亿个星系的位置和形状，数千颗超新星的光变曲线，以及超过1000颗系外行星的微透镜信号。这些测量要求宽视场仪器（WFI）具有前所未有的灵敏度和特性，特别是其检测器。WFIRST项目进行了广泛的探测器开发计划，以创建满足这些科学要求的焦平面阵列。这些原型探测器已被表征，并在相关的太空环境（热真空，振动，声学和辐射测试）中证明了其性能，将H4 RG-10的技术准备水平（TRL）提升到TRL-6。我们提出了这些TRL-6演示设备的性能特点。
英文摘要：
The Wide-Field Infrared Survey Telescope (WFIRST) will answer fundamental questions about the evolution of dark energy over time and expand the catalog of known exoplanets into new regions of parameter space. Using a Hubble-sized mirror and 18 newly developed HgCdTe 4K x 4K photodiode arrays (H4RG-10), WFIRST will measure the positions and shapes of hundreds of millions of galaxies, the light curves of thousands of supernovae, and the microlensing signals of over a thousand exoplanets toward the bulge of the Galaxy. These measurements require unprecedented sensitivity and characterization of the Wide Field Instrument (WFI), particularly its detectors. The WFIRST project undertook an extensive detector development program to create focal plane arrays that meet these science requirements. These prototype detectors have been characterized and their performance demonstrated in a relevant space-like environment (thermal vacuum, vibration, acoustic, and radiation testing), advancing the H4RG-10's technology readiness level (TRL) to TRL-6. We present the performance characteristics of these TRL-6 demonstration devices.
