noncoaxial opなし → table(引数だけで決まる op —— 画像やデータの入力を取らない)import fullseye as fs; fs.ledger.noncoaxial_system(elements=None, stop=None, object_mm=inf, wavelength_um=0.58756, index_object=1.0, field=(0.0, 0.0), image_mm=None, image_tilt=(0.0, 0.0), object_tilt=(0.0, 0.0)) (実装を直接呼ぶなら import raytrace3d; raytrace3d.noncoaxial_system(elements=None, stop=None, object_mm=inf, wavelength_um=0.58756, index_object=1.0, field=(0.0, 0.0), image_mm=None, image_tilt=(0.0, 0.0), object_tilt=(0.0, 0.0))、台帳から引くなら opsoptics.get("noncoaxial_system"))Build a validated non-coaxial sequential system (table) — surfaces, coordinate breaks, folds, plates.
elements is a list of dicts ("type" defaults to "surface"), or the dict returned by
raytrace.lens_system (converted exactly; its traces then equal raytrace’s to 1e-12):
{"type": "surface", "R", "t", "n", "k", "ap", "mirror", "asph", "decenter", "tilt", "coating",
"beamsplitter": {"R": r, "branch": "transmit"|"reflect"}} — as in raytrace.lens_system;
decenter / tilt act on that surface only. coating is used by the ghost analysis
(None / "bare", a material name = a quarter-wave single layer, [(material, nm), ...] from the
incident side, or {"R": r}).{"type": "break", "decenter": (dx, dy), "tilt": (ax, ay, az), "order": "xyz"|"zyx", "t"} — a
coordinate break (decenter, then rotate about x, the new y, the new z; degrees) that moves every later
surface; {"type": "break", "undo": j} is the exact inverse of break record j.{"type": "return", "to": j, "t"} — go back to the coordinate system at the entry of record j.{"type": "fold_mirror", "tilt": (ax, ay), "t", "ap", "R", "reflectance"} — a mirror tilted by
(ax, ay); the axis is reflected (45° folds by 90°) and t runs along the folded axis.{"type": "plate", "thickness", "n", "tilt": (ax, ay), "wedge": (wx, wy), "t", "beamsplitter": r,
"branch", "coating_front", "coating_back"} — a tilted plane-parallel (or wedged) plate, or a plate
beamsplitter; t is measured from the front vertex along the incoming axis (transmit branch) or
along the reflected axis (reflect branch).stop is the record index of the aperture stop (default: the first surface); field is
(fx, fy) (degrees for an object at infinity, mm otherwise); image_tilt / object_tilt tilt the
image / object plane about the local x and y axes (degrees; Scheimpflug). The last record’s t is the
distance to the image plane (None = the paraxial focus along the axis ray).
Default: a singlet f ≈ 100 mm followed by a 45° fold mirror (the image lands along +y).
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。 |
