The Cornu Spiral

Cornu 螺旋线

The Cornu spiral is a graphical aid for evaluating the Fresnel integrals which show up in the evaluation of the diffraction intensities for the Fresnel diffraction of the light from a slit. It lends itself to the calculation of diffraction from slits, barriers, and opaque strips.

Cornu 螺线是一种图形工具，用于评估在菲涅耳衍射中从狭缝发出的光的衍射强度所出现的菲涅耳积分。它适用于计算狭缝、障碍物和不透明条纹的衍射。

The eyes of the spirals at (.5,.5) and (-.5,-.5) represent image plane points at infinity.

螺旋在（0.5，0.5）和（-0.5，-0.5）处的眼睛代表无限远处的像平面点。

The V-value associated with a given image plane point is determined by the Fresnel geometry.
