Abstract: A two-dimensional image sensor is exposed under vacuum to an electron beam having passed through a specimen in an electron microscope to enable the image sensor to store the energy of the electron beam. Then, stimulating energy is applied to the image sensor to discharge the stored energy as light. The light discharged from the image sensor is photoelectrically detected to produce an image signal. A defocus value of the image is detected on the basis of the image signal. The image signal is also subject electrically to the Fourier transform to produce a converted image signal indicative of a ring pattern. The degree of one ring, the length of minor and major axes of the ring, and the angle of inclination of the major axis are computed from the converted image signal for computing currents to be fed to a stigmeter of the electron microscope to eliminate astigmatism.

Abstract: A two-dimensional image sensor is exposed under vacuum to an electron beam having passed through a specimen, and instantaneous light emitted from the image sensor upon exposure to the electron beam is detected with an image intensifier to reproduce an image observed to attain a desired focused condition and/or a desired field. After the image has been focused by the operator while observing the image, the image sensor is exposed under vacuum to an electron beam having been transmitted through the specimen to store the energy of the electron beam representative of the image of the specimen on the image sensor.
