To reveal the fundamental aspects hidden behind various biological,chemical and physical phenomena,the capability of acquiring images with an ultrafast temporal resolution is indispensable and highly desired.The imaging frame rate of traditional CCD and CMOS imager usually only reaches sub-MHz,which is limited by the tradeoffbetween sensitivity and integration time1.The pump-probe scheme is widely applied in scientific imaging for its high-temporal resolution of pico-second level2.Recently,to film the events in chemical reactions,pump-probe combined with scanning tunneling microscopy (STM) or X-ray schemes are proposed.
