正方形环形孔径夫琅禾费衍射光场的计算与模拟

iffraction of light in medicine, micro-optics, information encoding, information storage and optical communication has important applications. Kirchhoff diffraction formula adopted in this article, has been calculated when the unit amplitude plane monochromatic light normally incident to the square annularity aperture, caused by the Fraunhofer diffraction light field calculation and the use of software simulation Mathematica6.0 its diffraction pattern and the light intensity distribution curve, analysis of light diffraction pattern and the characteristics of the distribution curve, drawn to the calculation of the formula is correct and can be dealt with information from optical Fraunhofer diffraction basic ideas and methods.
