某型一维大摆角扫描器的总体设计

Overall Design of a Type of One-dimension Large Swing Angle Scanner

采用线列焦平面探测器成像须借助光机扫描覆盖视场,而高线性大摆角的扫描器是实现高性能扫描型热像仪的重要条件。针对基于某支撑技术而研究的大摆角扫描器做光机优化设计,对所需电机驱动转矩进行理论计算和选型,并用Motion进行仿真验证,验证结果能达到设计要求。

It’s necessary that optical and mechanical scanning is applied to cover the FOV in thermal imaging with linear FPA detector, so scanner with high linearity and large swing angle is an important requirement to realize high characteristic scanning thermal imager. This paper includes optical and mechanical optimization design of scanner with large swing angle and theoretic calculation about toque of such motor, therefore the selection is given. The simulation results with Motion show that it can meet the needs of design.
