一种新的TDI IRCCD驱动与测试系统设计

基于可视化交互式控制思想,本文提出了一种新的针对延时积分LRCCD的驱动与测试系统方案.不同于传统的驱动电路系统,该系统由主从两大系统构成,其中作为人机接口的主系统主要完成电参数的输入和测试结果的显示,而从系统一方面可根据主系统所设置的电参数自动产生高精度的任意可调驱动信号,另一方面则完成对LRCCD器件的电注入测试.实验结果表明新的设计有效地克服了传统设计所固有的缺陷,显著提高了系统的可靠性、灵活性和精度.

Novel Design of Drive and Test System for TDI IRCCD

Based on the idea of visual interactive control, a novel drive and test system for Time-delay Integration (TDI)IRCCD is presented. Being different from traditional drive circuit system, the newly developed system can accurately generate arbitrarily adjustable drive signals and feed back the device characteristic parameters, simultaneously. Especially, the system consists of two parts, which are Hog-computer-subsystem (HCS) and Slave-computer-subsystem (SCS). The HCS, being man-machine interface of the whole system, accomplishes parameter input and testing results display, while the SCS constructed with Single Chip Micyoco (SCM) and Field Programmable Gate Array (FPGA), fulfils the electronic parameter adjustment for drive signals according to the data sent from HCS or stored in data-store unit, and implements the electronic injection test for the IRCCD. It is validated that some intrinsic defects of the traditional design, such as less flexibility and poor reliability, are successfully eliminated in this new designed system.
