Kirchhoff's formula - Kirchhoff's formula

...According to Huygens' principle, the wave motion u ( Q ) at a point Q is uniquely determined by the value of the wave motion on the closed surface σ surrounding that point. The intensity distribution of the diffracted light can be calculated using Kirchhoff's formula, which mathematically expresses this. Here, k = 2π/λ 0 , N is the inward normal to the closed surface, and r is the distance measured from point Q to a point on the closed surface (Figure 2). ...

Japanese:

…ホイヘンスの原理から,ある点Qにおける波動u(Q)は,その点を囲む閉曲面σ上の波動の値から一意に決まる。回折光の強度分布はこのことを数式化したキルヒホフの式,から求められる。ここにk=2π/λ0であり,Nは閉曲面に立てた内向きの法線,rは点Qより測った閉曲面上の点までの距離である(図2)。…
