Pan-STARRS项目已经完成了其第一个1.4千兆像素镶嵌焦平面CCD相机使用60正交传输阵列（OTA）。这些设备是一系列计划开发批次中的第二批。几个新的属性被实施到他们的设计中，包括4个相位像素的探测器上的倾斜倾斜图像补偿，可选区域逻辑待机或活动操作，相对较高的输出放大器数量，关闭四边可对接封装和深耗尽结构。部署这些OTA的测试和运营挑战需要硬件和软件的增强和新方法。我们比较了性能实现与预测，并讨论了对天空的结果，开发的工具，缺点，以及未来的OTA功能和改进计划。
The Pan-STARRS project has completed its first 1.4 gigapixel mosaic focalplane CCD camera using 60 Orthogonal Transfer Arrays (OTAs). The devices are the second of a series of planned development lots. Several novel properties were implemented into their design including 4 phase pixels for on-detector tip-tilt image compensation, selectable region logic for standby or active operation, relatively high output amplifier count, close four side buttable packaging and deep depletion construction. The testing and operational challenges of deploying these OTAs required enhancements and new approaches to hardware and software. We compare performance achieved with that which was predicted, and discuss on-sky results, tools developed, shortcomings, and plans for future OTA features and improvements.
