Description
図６は、屈折素子（例えばレンズ３１３、３１５）の代わりに反射素子を使用する図４の瞳リレー３０７（例えば撮像経路）の代替構成を示す。図４と同様なすべての素子は、同様な参照符号を有し、上記したものと同様である。参照符号ＲＣは網膜共役面を示し、参照符号ＰＣは瞳共役面を示す。図示の目的のために、カメラ３０５は長方形センサ筐体として示され、カメラ３０５の内部概略図は、瞳３０９と共役な集束レンズ３４２及び網膜３０１と共役なセンサ（フォトセンサアレイ）３４５を示している。図示されるように、カメラ３０５は、２つのＬＥＤのみが示されているが、カメラの絞りに隣接するとともにカメラの絞りを中心に分散された複数の光源（例えばＬＥＤ３１１）を有し得る。例えば、カメラ３０５は、その絞りを中心に分散されたＬＥＤを有する内視鏡カメラとして構成され得る。本実装では、瞳リレーは第１の湾曲反射面３４１と第２の湾曲反射面３４３とからなる。例えば、第１の湾曲反射面３４１は放物面鏡であり、第２の反射面３４３は球面鏡であり得る。本光学系は人の眼３０３の網膜３０１をセンサ３４５上へ撮像し、瞳３０９をカメラ３０５の絞り（例えば瞳分割面）上へ撮像する。
FIG. 6 shows an alternative configuration for the pupil relay 307 (eg imaging path) of FIG. 4 using reflective elements instead of refractive elements (eg lenses 313, 315). All elements similar to FIG. 4 have similar reference numerals and are similar to those described above. Reference sign RC indicates the retinal conjugate plane and reference sign PC indicates the pupil conjugate plane. For purposes of illustration,
