One kind of 3-frames framing camera with ultra high-speed and high performance is developed for beam parameters measurement. The optical principle of the framing camera is basing on splitting the focused imaging light beam in the field of image space. It features good imaging quality and high optic efficiency. It consists of high speed shutter, scientific Charged Coupled Device(CCD) camera and the high speed controller. The shutter time and the frame interval time can be set independently. The effective image size is 25 mm in diameter. The highest shutter time is about 2 ns. The spatial resolution is about 30 lp/mm in image space.
