潜望镜的

Now you can keep your boat at periscope depth all day long!

现在，您可以让您的船民在潜望镜深度一天！

The Periscope Drawtube will be bent because of the water resistance in sailing and this bend will cause the error of star measurement. Due to its especial structure, contactless measurement is the only way to measure its bend degree. First this paper introduces the method by linear array CCD based on structure and light path; Second it expatiates linear array CCD work principle and driving scheduling with example of TCD1501C and the driving circuit by CPLD. The output signal of linear array CCD includes common disturbance so the differential amplifier is needed. In order to make the signal adapt to computer processing, a threshold circuit with Schmitt characteristic and the data process following threshold are given. At last, some key problems in application are given.

潜艇潜望镜的镜筒在航行时受到水的阻力会产生弯曲变形，这种变形会造成潜艇对星体测量的误差；由于镜筒结构的特殊性，对其弯曲程度的测量只能采用非接触方法；首先从结构和光路方面介绍采用线阵CCD作为检测元件实现对镜筒弯曲程度的测量；其次以东芝公司的线阵CCD（TCD1501C）为例阐述了其工作原理及驱动时序的控制要点，并介绍了基于可编程逻辑器件的线阵CCD的驱动电路；线阵CCD输出的信号中含有共模干扰，必须采用差分放大器将其抑制；为将信号转化为适合计算机处理的数字信号，文中给出了有一定实用价值具有施密特特性的二值化处理电路及二值化后的数据处理过程；最后阐述了在实际使用中的一些关键问题。
