摘要	In order to obtain high resolution aerial images, in addition to adopt high transfer function of optical system and high quality imaging medium, the exposure time of the shutter should be properly controlled, so as to make sure the appropriate exposure of the CCD sensor. The paper applies an aerial mapping camera shutter the structure and working principle of the mirror, presents the mirror shutter algorithm of the working period of luminous flux, on the basis of radiation theory. The paper also analyze the transfer relations of the object and image of the light energy on the optical system with large field of view, short focal length and large relative aperture. The experimental results show that the illumination precision of image plane improved by 8.9%, compared with the traditional algorithm and the gain exposure of CCD sensor is closer to the actual light energy. In addition, these design can also provide theoretical reference for image uniformity correction, CCD gain adjustment and variable density neutral filter processing.
