...The eikonal is useful for analytically discussing geometrical optical imaging, and the independent variables that describe it include the position coordinates P 0 ( x 0 , y 0 , z 0 ), P( x , y , z ), as well as the optical direction cosines ( p 0 , q 0 , r 0 ) and ( p , q , r ), which are the direction cosines of the light rays multiplied by the refractive index of each space. The above V is called the point eikonal (expressed in position coordinates), but there are also the angular eikonal T ( p 0 , q 0 ; p , q ), which uses the optical direction cosines, and the mixed eikonal W ( p 0 , q 0 ; x , y ) and W ′ ( x 0 , y 0 ; p , q ), which uses both position coordinates and optical direction cosines. It is difficult to determine the eikonal precisely for an actual optical system, but it is possible to obtain it approximately and discuss aberrations analytically. *Some of the terminology explanations that mention "Kaku Ikonal" are listed below.

…アイコナルは解析的に幾何光学的結像を論ずるので便利であり,これを記述する独立変数としては,位置座標P0(x0,y0,z0),P(x,y,z)の組のほかに,光線の方向余弦にそれぞれの空間の屈折率をかけた光学的方向余弦(p0,q0,r0)と(p,q,r)をとることもできる。前出のVは点アイコナルと呼ばれる(位置座標で表される)が,このほかに光学的方向余弦を用いる角アイコナルT(p0,q0;p,q),位置座標と光学的方向余弦の両者を用いる混合アイコナルW(p0,q0;x,y)およびW′(x0,y0;p,q)などがある。実際の光学系に対してアイコナルを厳密に求めることは難しいが,近似的にこれを求めて収差を解析的に論ずることができる。… ※「角アイコナル」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
