longitudinal aberrationsとは 意味・読み方・使い方

The optical pickup is also equipped with an element 5 for varying a refractive index profile, i.e., an element capable of compensating spherical aberrations or the like in each optical face by varying a refractive index profile, canceling and compensating the axial chromatic aberrations generated in other than the objective lens using longitudinal chromatic aberrations generated in the diffraction face.例文帳に追加

また、屈折率分布を変化させて各光学面で生ずる球面収差等を補正できる屈折率分布可変素子５を備え、対物レンズ以外で発生する軸上色収差を回折面で発生する軸上色収差により相殺補正する。 - 特許庁
