Abstract
In a system for recording and reproducing an electron microscope image, a two-dimensional sensor for storing electron beam energy is exposed to an electron beam passing through a sample in a vacuum to have the electron beam energy stored in the two-dimensional sensor. The two-dimensional sensor is then exposed to light or heated while the vacuum is maintained to release the stored energy as light emission. The light emitted by the two-dimensional sensor is photoelectrically detected to obtain an electric signal for reproducing a visible image.
