摘要: An ultrafast framing camera with a pulse-dilation device and a microchannel plate (MCP) imager as well as an electronic imaging system is reported. The camera achieves a temporal resolution of 10 ps by using a pulse-dilation device and a gated MCP imager, and a spatial resolution of 100 μm by using an electronic imaging system composed of combined magnetic lenses. The spatial resolution characteristics of the camera are theoretically and experimentally studied. The results show that the camera with combined magnetic lenses could reduce field curvature and acquire a larger working area. A working area 53 mm in diameter has been achieved by applying four magnetic lenses to the camera. Furthermore, the camera is used to detect X-rays produced from a laser targeting device. The diagnostic results show that the width of the X-ray pulse is about 18 ps.
