The panel (square, side panel_mm, unfolded distance panel_distance_mm from the part through the 45-degree half mirror) lights the part by one reflection (R); the camera (pinhole at camera_distance_mm, or telecentric) looks through the mirror (T = 1 - R - A).
Budget: round_trip = R T (1/4 for the default lossless 50/50 mirror; splitter_reflectance /
splitter_transmittance carry R and T under the names the optscene coaxial light reads),
optimum_reflectance = (1 - A) / 2, max_round_trip =
(1 - A)^2 / 4 (0.25 for a lossless mirror), ghost_ratio = T^2 r_b / R (the back-surface
reflection of the plate, relative to the front reflection, on the illumination leg) and
ghost_offset_mm = 2 t tan(theta_r) cos 45 deg (its lateral shift; sin theta_r = sin 45 / n).
Image (camera view, shape pixels over a square field of half-width field_mm):
part="mirror": a specular part shows the panel itself, so the image is
R T L(panel point) with the panel point x (1 + h_panel / h_camera) (x for a telecentric lens) —
the panel’s non-uniformity is imaged one to one (like critical illumination) and the field
goes dark beyond vignetting_edge_mm = (panel / 2) / (1 + h_panel / h_camera).part="matte": a Lambertian part (albedo 1) returns R T E / pi, with E the irradiance of the
panel (numerical sum over an n_panel x n_panel grid; the closed form for a uniform rectangle
is matte_centre_closed). n_panel = None uses 32.panel_radiance: None = uniform 1, or a 2-D map laid over the panel square.
Returns also image, uniformity (:func:illumination_uniformity of the central 80 %; None when
T = 0 and the image is dark by the budget, not by the geometry),
panel_scale (1 + h_panel / h_camera).
Raises ValueError: R + A > 1, R = 0, a panel farther than the camera, unknown part.
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。 |
