Study on the Slit Systems for X-Ray Back Reflection Camera

In the stress analysis by X-rays, the detectable volume is the function of the area irradiated by X-rays and the depth of penetration of X-rays. It involves a number of crystals having the specific diffraction plane which satisfy the Bragg's diffraction condition in regard to incidental X-rays. Therefore, if the orientation of each crystal in the metal is statistically uniform, we can postulate that the macroscopic gauge length for the stress analysis equals the area irradiated by X-rays.
