light_transport 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.groove_profile(kind='vgroove', n_patches=240, width=1.0, angle_deg=None, floor_frac=None, vertices=None) (実装を直接呼ぶなら import lighttransport; lighttransport.groove_profile(kind='vgroove', n_patches=240, width=1.0, angle_deg=None, floor_frac=None, vertices=None)、台帳から引くなら opsoptics.get("groove_profile"))Split a concave cross-section (V-groove, circular trough, fillet or any concave polyline) into patches, one camera pixel column each.
The part is extruded along the groove axis; the cross-section is a
function z(x) that is concave (a valley), viewed by an orthographic
camera from straight above, one patch per pixel column. The built-in
shapes are sampled at n_patches + 1 uniform x (a kink between two
samples is cut by the chord), rims at z = 0. angle_deg is the
shape’s defining angle and floor_frac the share of width that is a
flat floor; None takes the per-shape default.
"vgroove" — two plates with full opening angle angle_deg
(default 90 = an inner corner tipped by 45 degrees, range [5, 175]),
meeting at the bottom or, with floor_frac > 0 (default 0), on a
centred flat floor (a trapezoidal groove). With no floor and an even
n_patches the vertex is a patch edge."trough" — circular arcs that reach a wall slope of angle_deg
at the rims (default 60, range (0, 90)), with an optional centred
floor (default 0)."fillet" — a flat floor over the left floor_frac of the width
(default 0.5, range (0, 1)), then a circular arc tangent to it rising
to a wall slope of angle_deg at the right rim (default 70, range
(0, 85]) — a solder-fillet-like meniscus. The floor’s left end is open."polyline" — vertices (P+1, 2) as (x, z).Returns a dict (a table) with kind = "lt_profile", shape,
vertices (P+1, 2), centers (P, 2), normals (P, 2, unit, pointing
up out of the material), lengths (P,) and x_centers (P,).
Raises ValueError: unknown kind; n_patches not an integer in
[2, 2048]; non-positive or non-finite width; angle_deg or
floor_frac outside the shape’s range; vertices given for a built-in
shape or missing for "polyline"; vertices that are not a concave
function z(x) (x not strictly increasing, or a convex turn).
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。 |
