    摘要: Each of two-dimensional sensors is exposed to an electron beam, which has passed through a sample, in a vacuum in order to store the energy from the electron beam on the two-dimensional sensor, and is then exposed to light or heat in order to release the stored energy as emitted light. The emitted light is photoelectrically detected and an image signal is thereby obtained which represents an electron microscope image of the sample. Read-out conditions which are to be used when the emitted light is detected are determined from an electron beam exposure amount which was set when the energy from the electron beam was stored on each two-dimensional sensor. Signals representing the read-out conditions determined for the two-dimensional sensors are stored in a storage device so that it is clear which read-out conditions correspond to which two-dimensional sensor. When light emitted by a two-dimensional sensor is to be detected, a signal which represents the read-out conditions corresponding to the two-dimensional sensor is read from the storage device, and the read-out conditions are set.

    摘要: A transmission-type electron microscope using a sensitive two-dimensional sensor in its micrograph-taking section acts as a recording medium for an electron beam. When the sensor is illuminated with an electron beam, it stores the energy of the beam. When the sensor is subsequently illuminated with light, it releases the stored energy as light. In accordance with the invention, at least a portion of the micrograph-taking section includes a member for reducing the amount of x-rays produced or a member for absorbing x-rays to shield the sensor from x-rays.

    摘要: In a system for outputting an electron microscope image, a two-dimensional sensor for storing electron beam energy thereon is exposed to an electron beam passing through a specimen in a vacuum to have the electron beam energy stored on the two-dimensional sensor, and is then exposed to light or heat to release the stored energy as light emission. The emitted light is photoelectrically detected to obtain image signals, and an electron beam image of the specimen is output on the basis of the image signals. The specimen is divided into a plurality of divisions, and the storage of the electron beam energy is carried out for each of the divisions. The image signals obtained at the divisions are combined to form composite image signals that represent an overall specimen image formed by a group of the divisions, and the image signals at the divisions are corrected so that signal values of the boundary areas of adjacent divisions become approximately equal to each other.

    摘要: A transmission-type electron microscope comprises a lens system including an electron gun for producing an electron beam that is focused and directed to a specimen. The lens system forms a magnified electron optical image of the specimen from the electron beam transmitted through the specimen. A two-dimensional sensor is mounted in the plane in which the magnified image is formed, the sensor acting to store the energy of the electron beam impinging on it and to release the stored energy as light when illuminated with light or heated. An electron beam-deflecting means is mounted in the lens system and acting to tilt the focal plane in which the magnified lens image is formed, in such a way that a straight line extending from the main optical axis of the electron beam between the electron gun and the specimen does not interset the two-dimensional sensor.

    摘要: A stimulable phosphor sheet is exposed to an electron beam having passed through a specimen in an electron microscope to record a first magnified image of the specimen on the sheet. A stimulating energy is applied to the sheet for discharging light therefrom which represents the first magnified image. The light discharged from the image sensor is photoelectrically detected to reproduce the first magnified image which can be observed to attain a desired focused condition and/or a desired field on the electron microscope. Then, the same or another stimulable phosphor sheet is exposed to the electron beam to record a second magnified image of the specimen on the sheet, and the second magnified image is reproduced as a final image under the desired focused condition and/or with the desired field.

    摘要: An electron microscope has a two-dimensional sensor located at the image-formation plane. The two-dimensional sensor stores electron beam energy and emits light upon exposure to light or heat. The filament is located at a position displaced from the principal optical axis of the electron beam so that the image of the filament may not be recorded on the two-dimensional sensor. The two-dimensional sensor is, for example, made of stimulable phosphor.

    摘要: A two-dimensional image sensor such as a stimulable phosphor sheet is exposed under vacuum to an electron beam that has passed through a specimen to cause the two-dimensional image sensor to store the energy of the electron beam, then stimulating energy is applied to the two-dimensional image sensor for discharging light therefrom which represents the stored energy of the electron beam, and the light discharged from the two-dimensional image sensor is photoelectrically detected to produce an image signal. A reference image signal is also produced in a similar manner by exposing the two-dimensional image sensor to an electron beam that has not passed through the specimen. One of the first-mentioned image signal and the reference image signal is subtracted from the other per pixel to generate a difference signal, from which an electron microscope image of the specimen is reproduced.

    摘要: 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. Then, stimulating energy is applied to the image sensor for discharging light therefrom which represents the stored energy of the electron beam. The light discharged from the image sensor is photoelectrically detected to reproduce the transmitted electron-beam image of the specimen as a final output image thereof under the desired focused condition and/or with said desired field.

    摘要: 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.
