| 20130195254 | X-RAY CONTROL UNIT USING MONOCRYSTALLINE MATERIAL - An X-ray control unit using a monocrystalline material which controls only a specific wavelength of X-rays, by using the monocrystalline material as a filter. The X-ray control unit includes a light source configured to generate X-rays, an X-ray control filter formed of a monocrystalline material having grown in one direction and configured to filter the X-rays generated by the light source to reflect and transmit characteristic X-rays, and an adjustor configured to adjust the light source and the X-ray control filter to arbitrary angles. Since X-rays having a specific wavelength can be selectively used by using a filter, the X-rays can be easily controlled and their intensity can be easily regulated. A characteristic line of the X-rays can be controlled and their intensity can be regulated without directly controlling an X-ray source. | 2013-08-01 |
