THE SIMILARITY OF FRESNEL DIFFRACTION UNDER SCALE-DISTANCE TRANSFORM |
| |
| Abstract: | While previous studies show that Fresnel diffraction has no similarity under scale transform or distance transform,this paper further indicates that Fresnel diffraction does have similarity under scale-distance transform.This new property has been theoretically analyzed and practically discussed.Some examples of its applications,such as in diffraction theory,diffraction pattern recording and observation,and holography,are also given. |
