| Abstract: | The CCD-type aerial reconnaissance camera has large memory capacity,which can take thousands of images each time with the shutter exposing frequently.Therefore,the shutter should have high reliability and long service life.A new type of high reliability,long life focal plane curtain shutter was designed.The curtain was made of titanium foil and no gear needed,thus the traditional shortcomings of the many types of shutter were overcome,and the life of the shutter curtain was guaranteed.Through the DSP control of the entire system,the control precision was improved.The experimental result showed that this curtain-type shutter ran steadily and reliably.The exposure time can be adjusted continuously from 1/1200 s to 1/150 s.The effect of exposure time accuracy of the shutter is below 6%.And the useful life attains three hundred thousand times. |
