This paper describes an aerial digital camera with large format of view using Area Scan color CCD as imaging medium.Large field and low distortion of optical lens is emphatically studied.The symmetrical Russar optical system not only ensures a wide field of view,but also reduces the distortion mostly.In order to improve imaging resolution and imaging quality of aerial photography image,a forward imaging moving compensation device has been designed to provide microscopic operations.To adapt to illumination change and obtain appropriate image overlap.It is adopted a two-blade mechanical central shutter which can fit for wide exposure range while ensuring the homogeneity of the detector exposure.According to the imaging test on ground and in flight,the camera′s static resolution reaches the CCD′s characteristic frequency.Obtaining clear color images in aerial tests proves that the camera′s technical parameters can meet the requirements.Currently the camera is being used in remote sensing survey in our country.
