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.

To improve the stability of Arcjet discharge plasma in low current and high voltage mode, research on the demand of output characteristics of Arcjet Power Conditioning Unit was conducted. In this paper, based on PWM invertors and current mode control, using MOSFET as the main power device, an Arcjet Power Conditioning Unit was developed. Through adding a closed loop feedback circuit of output voltage, it can make the output characteristics of PCU be positive resistance to ensure the stability of Arcjet discharge plasma. The experiment indicates that this PCU can make Arcjet engine work at high voltage mode (100 V, 10 A) and ensure the stability of arcjet discharge plasma. Finally, it provides the experimental data of Arcjet when working.
