    摘要: An electron energy filter includes a first pair of magnetic poles for generating a first deflecting magnetic field and a second pair of magnetic poles for generating a second deflecting magnetic field in the same direction as the first deflecting magnetic field. The incident electrons are deflected about 90.degree. with a trace radius of AM1 through the effect of the first deflecting magnetic field, passed through a free space having a distance DL2 that is about a half of the trace radius AM1 and then are incident to the second deflecting magnetic field. The electrons are deflected about 180.degree. with a trace radius AM2 that is about a half of the curvature radius AM1 and are passed through the free space DL2. Then, the electrons are incident to the first deflecting magnetic field again where those electrons are deflected about 90.degree.. The deflected electrons are traveled like a gamma trace so that those electrons outgo in the same direction as the incident one. This filter so designed is made compact and to have a smaller aberration.

    摘要: A transmission electron microscope is capable of correcting, with high efficiency and high accuracy, an electron energy loss spectrum extracted from each of measured portions included in an electron energy loss spectral image with two axes representing the amount of an energy loss and positional information on a measured portion. The transmission electron microscope has an electron spectroscope and a spectrum correction system. The spectrum correction system corrects a spectrum extracted from each measured portion included in an electron energy loss spectral image acquired from a sample based on a difference between a spectrum extracted from a standard portion of a standard spectral image and a spectrum extracted from a portion different from the standard portion.

Method and apparatus are offered which correct distortion in a spectral image with high efficiency and high accuracy, the image being formed by the two orthogonal axes (the axis of the amount of energy loss and the axis of positional information).

    摘要: Drift generated at the time of photographing a TEM image is corrected simultaneously with photographing, so that a TEM image free form influence of drift is photographed. While the TEM image is recorded, drift in the place out of the view field subjected to recording is measured from moment to moment by another TV camera or a position sensitive detector. Drift is corrected by the movement of the specimen due to a specimen holder or by the movement of the image due to an image shift coil.

    摘要: A method and apparatus for measuring the physical properties of a micro region measures the two-dimensional distribution of stress/strain in real time at high resolution and sensitivity and with a high level of measuring position matching. A sample is scanned and irradiated with a finely focused electron beam (23, 26), and the displacement of position of a diffraction spot (32, 33) is measured by a two-dimensional position-sensitive electron detector (13). The displacement amount is outputted as a voltage value that is then converted into the magnitude of the stress/strain according to the principle of a nano diffraction method, and the magnitude is displayed in synchronism with a sample position signal.
