    In view of the inconsistent perspective in target images obtained by pinhole array for traditional X-ray gating micro channel plate (MCP) framing camera, an implement method of X-ray framing camera with single perspective is proposed. At the electro-optic intersection in electrostatic focus image tube, the electrons carry holographic information, and can be divided into multiple output images with single perspective, subsequently a gated MCP unit is matched with the frame to enhance the target image. Compared with the traditional gated MCP framing camera, the designed framing camera realizes identity of image perspective and avoids direct light′s excitation on screen, and a higher signal-to-noise ratio is obtained. The designed framing image tube has an effective input working diameter of 40 mm, an output image diameter of 40 mm, a magnification of 1.29, the center spatial resolution of 60 lp/mm in theory, the marginal spatial resolution of 26 lp/mm, and the geometric distortion of less than 15%. Single frame exposure duration is determined by shutter pulse time of gated MCP framing unit. This method is an effective way to realize identity of image perspective for X-ray framing image camera.
