2. 第2の項、2a(n−1)Δy:位相に敏感なデバイス(例えば干渉計)を除き光学系において利用されそうにない、線形ピストン位相シフト(ゼルニケ項Z0、表を参照);
3. 第3の項、6c(n−1)[y2+z2]Δy:変動する倍率を有する放物線レンズZ4。本実施形態では、レンズの焦点距離はF=[12c(n−1)Δy]−1であり、A=3cであるときに米国特許第3,305,294号に記載のものと一致する;
4. 第4の項、10g(n−1){y2+z2}2Δy:三次球面収差である二次の項Z12は、Δyと共に線形に変化する。球面収差の振幅は:A12=10g(n−1)Δ/λ(ここで、λは光の波長)である。
1. 第1の項、(n−1)(h1+h2):定数ピストンZ0;
2. 第2の項、A(n−1)(y2+z2)Δx:可変焦点放物線レンズZ4。レンズの焦点距離はF=[2A(n−1)Δx]−1;
3. 第3の項、
4. 最後の項、(n−1)R(x、y、Δx):高次のシフト依存性の寄与Δx3、Δx5、等の寄与。Δx<<1である場合、これらの寄与は無視できるほど小さく、実用目的のために省略することができる。
焦点ずれおよび球面収差項のみを保持し、上記のように特定されるサグ関数S(x、y)は以下の形をとる:
