Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
75 words
A method of recording and reproducing an electron microscope image, which comprises the steps of: i) exposing a two-dimensional sensor for storing electron beam energy to an electron beam passing through a sample in a vacuum to have the electron beam energy stored in said two-dimensional sensor, ii) exposing said two-dimensional sensor to light or heating it in said vacuum to release the stored energy as light emission, and iii) photoelectrically detecting the emitted light.
Claim 2
Independent Claim
75 words
A method of recording and reproducing an electron microscope image, which comprises the steps of: i) exposing a two-dimensional sensor for storing electron beam energy to an electron beam passing through a sample in a vacuum to have the electron beam energy stored in said two-dimensional sensor, ii) exposing said two-dimensional sensor to light or heating it in said vacuum to release the stored energy as light emission, and iii) photoelectrically detecting the emitted light.
Claim 3
Dependent Claim
73 words
A method as defined in Claim 1 wherein a stimulable phosphor sheet is used as said two-dimensional sensor, said stimulable phosphor sheet is exposed to said electron beam passing through said sample in said vacuum to have the electron beam energy stored in said stimulable phosphor sheet, said stimulable phosphor sheet is then scanned with stimulating rays or heat rays in said vacuum to emit light, and the emitted light is detected photoelectrically.
Claim 4
Dependent Claim
24 words
A method as defined in Claim 2 wherein said stimulable phosphor sheet is an endless belt-like sheet and is rotatably positioned around rollers. ,
