【摘要】 针对红外成像系统常用光机扫描器的不足,提出了没有机械运动部件的全固态电光扫描器设计方法,给出了几种透射式固态电光扫描器结构,主要包括扫描列阵、耦合波导和控制电路三个部分。工作原理是:通过控制电路顺序控制各扫描单元光信号的传输,再通过耦合波导将光信号耦合到探测器上实现扫描成像。扫描列阵将完整图像分割成图像单元,耦合波导将空间位置不同的图像单元耦合到红外焦平面探测器上,控制电路用来控制扫描列阵各图像单元的工作状态。这种扫描器体积小、重量轻、结构紧凑,采用与红外焦平面探测器制作工艺相似的半导体制作工艺,具有与探测器集成的技术基础,控制起来更加方便。更多还原

【Abstract】 To improve the performance of the opto-mechanical scanner used for IR imaging system,a new kind of design method for fully solid-state electro-optic scanner was presented,which had no movable elements,and then serial kinds of their configurations were discussed.The scanner mainly consisted of scanning array,coupling waveguide and control circuit.Its principle was that the light signal can be transmitted by controlling each scanning units on scanning array orderly and coupled in IRFPA by coupling waveguide.The scanning array divided the full images into equal pieces,the coupling waveguide coupled light signal of different positions in IRFPA,and the control circuit controlled the states of each scanning units.The scanner has some merits,such as fully solid-state structure,smaller bulk,lighter mass,compatibility,semiconducor manufacture techniques similar to that of IRFPA,potential abilities to integrate with detectors or some other parts of infrared imaging system.更多还原
