Analysis on the subpixel dynamic imaging system of a high speed TDI CCD camera

Subpixel dynamic imaging technology is the very valid new method of reducing the size of camera and improving the spatial resolution. A novel method that combined the subpixel dynamic imaging technique with the TDI CCD camera is presented. The method can improve imaging system's resolution sharply, while keeping the same size of TDI CCD sensor and focal length of the camera system. In order to confirm the method's validity the MTF of the subpixel dynamic imaging system is analyzed. The result shows that the resolution of subpixel dynamic imaging system can be improved 1.6 times as many.
