Abstract
PURPOSE: To obtain an excellent picture by relieving the defect of a detector or target surface at a specific part, by scanning a plural number X-ray micro-beams while slightly shifting the positions at every measurement period.
CONSTITUTION: In the equipment which allows X-ray beams to scan on subject 7 at every, for example, one degree while ring holder 2 equipped with X-ray micro- beam generator 1 and X-ray detector 9 between subject 7 is rotating, deflecting- signal generating circuit 11 operates pinhole lens driving mechanism 14 so that pinhole 6 moves in the reverse direction of the rotation of holder 2 at period T (while holder 2 rotated once), the period-T saw-tooth wave composed of three kinds of component waves A, B and C which rise at the same time to increase end voltages gradually are sup-plied to deflector 8, and electron beams E and B are caused to scan on target 5 so that subject 7 will be scanned three times by X-ray micro- beams within period T. Threrfore, the position of detector 9 for X rays irradiated upon subject 7 three times in one period is shifted as shown by A", B" and C", so that a signal error can be relieved which bases upon the defect of the specific detector.
