Vera C.的电光测试和表征。Rubin Observatory Legacy Survey of Space and Time（LSST）相机焦平面由205个电荷耦合器件（CCD）组成，布置在21个独立的筏塔模块（RTM）和4个角筏塔模块（CRTM）中，目前正在SLAC国家加速器实验室进行。使用一组定制的光学投影仪进行摄像头传感器的测试，该光学投影仪被设计为用一系列光照明模式照亮整个焦平面或焦平面的特定区域：串扰投影仪、平面照明器投影仪和点网格投影仪。除了测量串扰、线性度和满阱之外，使用点栅投影仪投影真实大小的源的能力，还可以在相机第一次发光之前对仪器特征进行独特的测量，例如延迟电荷失真、由于传感器效应引起的天体测量偏移以及更亮-更胖效应。在这里，我们提出了光学投影仪的设计和使用，电光测量，以及如何将这些结果用于测试和改进LSST相机仪器签名去除算法。
英文摘要：
Electro-optical testing and characterization of the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) Camera focal plane, consisting of 205 charge-coupled devices (CCDs) arranged into 21 stand-alone Raft Tower Modules (RTMs) and 4 Corner Raft Tower Modules (CRTMs), is currently being performed at the SLAC National Accelerator Laboratory. Testing of the camera sensors is performed using a set of custom-built optical projectors, designed to illuminate the full focal plane or specific regions of the focal plane with a series of light illumination patterns: the crosstalk projector, the flat illuminator projector, and the spot grid projector. In addition to measurements of crosstalk, linearity and full well, the ability to project realistically-sized sources, using the spot grid projector, makes possible unique measurements of instrumental signatures such as deferred charge distortions, astrometric shifts due to sensor effects, and the brighter-fatter effect, prior to camera first light. Here we present the optical projector designs and usage, the electro-optical measurements and how these results have been used in testing and improving the LSST Camera instrumental signature removal algorithms.
