PURPOSE: To obtain immediately the result of observation of a Kossel pattern, by storing the electric signal of observation of the Kossel pattern into the memory to increase the image contrast and then giving a process to the signal read out of the memory.
CONSTITUTION: Sample 4 forms a Kossel pattern on image screen 51 of X-ray image intensifier 5 by the impulse of the electron beam radiated from electronic gun 1. The output of intensifier 5 is converted into the digital signal via an A/D converter and then stored in image memory 6. Thus the contrast of the Kossel pattern is increased at memory 6. The storage of memory 6 is read by computer 7, and then, e.g., the curvature of the curve of the Kossel pattern is calculated. At the same time, the signal read out is converted into the analog signal. Then the Kossel pattern is displayed through display cathode-ray tube 8.
