kind:
"point" — one emitter at position (default (0, 0, height_mm))
pointing straight down."ring" — n emitters on a circle of radius_mm at height_mm,
each tilted toward the axis by tilt_deg (default: aimed at the origin,
so the ring’s elevation angle is atan(height/radius); low
height/radius = dark field, high = bright field)."bar" — n emitters along a line of length_mm parallel to x at
y = radius_mm, z = height_mm, aimed at the origin line."dome" — n emitters spread over a hemisphere of radius_mm
(Fibonacci lattice, zenith angles 20°–85°), each pointing at the centre:
the diffuse, shadow-free illumination of a dome light."coaxial" — a disc of n emitters of radius radius_mm at
height_mm pointing down: the diffuse area source a beam splitter folds
onto the viewing axis. Put it at the camera height with a radius of at
least twice the part size, so that every point of a flat glossy part
sees the source in its mirror direction (a small source at the camera
gives one bright spot, not a field-wide glare). The dict carries an
area record so :func:defect_contrast takes the specular glare from
the disc’s uniform radiance L = n I0/(π r²) by a mirror-hit test
instead of a point sum that cannot resolve a narrow lobe."backlight" — n × n emitters on a square of side 2·radius_mm
at z = −height_mm pointing up: the part is seen in silhouette."custom" — emitters (N,3) and directions (N,3) given explicitly.intensity is the radiant intensity of one emitter on its axis (arbitrary units), cos_exponent the Lambertian order of its angular distribution (1 = ideal Lambertian LED; ~2–4 for a lensed LED with a narrower beam).
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。 |
