For surface records i < j (refracting surfaces and beamsplitters; nominal mirrors only as the parts of
the path they already are), the light runs to j, reflects, crosses j−1 … i+1 backwards, reflects at i
and runs on to the image plane — N(N−1)/2 paths. The nominal bundle (same launch as the image) is
traced along each path with real rays. Per ghost:
energy_ratio — ghost energy / image energy = R_i·R_j·Π T over the ghost path ÷ Π T over the
image path; R from surface_reflectance (the media of the prescription and coatings:
a coating for all surfaces, or {record: coating}; records may carry their own coating), at the
angle of incidence of the field’s chief ray on each surface (unpolarised; a 45° beamsplitter plate is not
treated as normal incidence);focus_offset_mm — the ghost’s best focus relative to the image plane (along the image normal;
negative = in front of the sensor), radius_mm (RMS) / max_radius_mm on the image plane,
centroid_xy (image-plane local) and offset_xy (from the image’s chief ray — where the false
copy lands relative to the true image);point_ratio — ghost irradiance / image irradiance for a point source whose image fills one
pixel_mm disk: energy_ratio · (pixel / max(pixel, radius))²;extended_ratio — the same for a uniform extended scene: energy_ratio · |det J_image| / |det J_ghost|
(the ghost spreads the scene over its own magnification); jacobian is J_ghost (image-plane position
of the ghost’s chief ray per unit field, 2×2; image_jacobian the image’s own).Rows are sorted by point_ratio (ties by the declared order). n_pairs = N(N−1)/2.
optics の全 op は入力を検証してから計算する(黙って通さない):
_mm / _um / _deg / _mrad。mm と µm の取り違えは crash ではなく「もっともらしく間違った答え」なので、名前で防ぐ。大きさから単位を推測する処理は一切しない。ValueError — float('50') は成功してしまうため、未パースの設定値が長さとして通り抜ける(実測: thin_lens('50', '200') がもっともらしい 66.667 mm を返していた)。bool も True == 1 の暗黙昇格として拒否。ValueError(実数枠のみ。虚部の無言切り捨て・マスク剥がしを拒否)。NaN/Inf は全入力で ValueError。depth_of_field の過焦点距離以遠の far_mm = inf(それが過焦点距離の定義)と gaussian_beam のウエストでの wavefront_radius_mm = inf(平面波面の曲率半径)。どちらも有限の相棒(far_is_infinite / curvature_per_mm)を併せて返す。それ以外の無言 NaN/Inf は内部で検出して ValueError —「float64 が溢れた」と「答えが無限大」は別の主張なので、後者の顔で前者を返さない。optics.MAX_GRID(4096)、供給された場/PSF/開口は optics.MAX_FIELD_ELEMENTS(2^24)、ABCD 素子列は optics.MAX_SYSTEM_ELEMENTS(1024)、Zernike は MAX_ZERNIKE_TERMS(512)/ MAX_ZERNIKE_ORDER(40)/ MAX_ZERNIKE_BASIS(2^25)。小さな引数から巨大な内部確保が起きる経路(実測: n_max=40 × 4096² で 108 GB)を fail-closed で塞ぐ。| 物理的に不可能な状態も拒否: 偏光度 > 1 の Stokes ベクトル、負の透過率、負の強度、n- | m | が奇数などの不正な Zernike 添字。 |
