lensrender optable → tableimport fullseye as fs; fs.ledger.bokeh_shape(system, field_xy_mm=None, defocus_mm=0.5, pupil_samples=512, object_mm=None, wavelength_um=None, grid=64) -> 'dict' (実装を直接呼ぶなら import lensrender; lensrender.bokeh_shape(system, field_xy_mm=None, defocus_mm=0.5, pupil_samples=512, object_mm=None, wavelength_um=None, grid=64) -> 'dict'、台帳から引くなら opsoptics.get("bokeh_shape"))The out-of-focus footprint of a point source - the intersection of the pupil images, the cat’s eye -> dict.
The point sits at field_xy_mm in the object plane at object_mm (a height in mm; for an object at infinity a pair of angles in degrees;
default: (0, 8) degrees for an object at infinity, a height of 5 % of the object distance otherwise), the sensor is defocus_mm behind the system’s image plane.
A hexapolar pupil bundle of about pupil_samples rays is traced forward (raytrace.ray_bundle, which stops a ray at every semi-diameter);
the rays that get through land on the shifted sensor and their convex hull is the footprint. The table has polygon_xy_mm (the hull,
counter-clockwise, relative to its centroid, on the sensor axes), mask (a grid x grid boolean image of the footprint, extent_mm wide),
area_mm2, the same for the on-axis point (axis_area_mm2), area_ratio (cat’s eye / on-axis disc), vignetting_factor (the share of the pupil
area that gets through relative to the axis, from the ray bundle), n_valid, centroid_xy_mm, symmetry_error_mm (how far the footprint is from its mirror image
about the meridional plane, 0 in exact arithmetic) and the footprint points points_xy_mm. The geometric defocus disc of a point on axis has the
diameter 2 |defocus| NA' (tested). The system must be axisymmetric (the field is traced along +y and rotated).
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。 |
