摘要： A radiation image recorded in a stimulable phosphor is read out by stimulating the stimulable phosphor by use of stimulating rays such as visible light or infrared rays. Upon stimulated, the stimulable phosphor emits light which is detectable by a photosensor. The radiation image readout device includes a photosensor for detecting the light emitted by the phosphor, and a reflecting optical element like a mirror located between the phosphor and the photodetector for reflecting stimulating rays advancing between the phosphor and the photosensor toward the phosphor. The reflecting optical element has a very small size not to intercept the light emitted by the phosphor and detected by the photosensor as much as possible.

摘要： In a method of recording a radiation image by use of a stimulable phosphor in which the stimulable phosphor is first exposed to an imagewise radiation to store the energy of the radiation and then is exposed to stimulating rays to emit light in accordance with the energy stored therein, the instantaneous emission of light emitted upon exposure of the stimulable phosphor to the radiation is detected to measure the level of the energy of the radiation stored in the phosphor. The instantaneous emission is detected by a photosensor which is located behind the phosphor. The output of the photosensor is utilized to control the density and/or contrast of the final image recorded on a photographic film which is recorded by use of the light emitted by the phosphor upon stimulated.

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： An acoustooptic image can be formed by using a plate-like image sensor capable of increasing its optical density upon exposure to a radiation. The image sensor is exposed to a radiation bearing image information to record the image information on the image sensor. Then, pulsed light is applied to the image sensor to enable the same to generate a pressure wave commensurate with the recorded image information. The pressure wave is detected in synchronism with the pulsed light and converted into an electric signal, from which an image signal is reproduced. The image signal may be displayed on a CRT, or recorded on a magnetic recording medium, or reproduced on a photographic material.

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.
