lensfile 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.lens_file_read(source=None, allow_partial: 'bool' = False, glass_dir=None) -> 'dict' (実装を直接呼ぶなら import lensfile; lensfile.lens_file_read(source=None, allow_partial: 'bool' = False, glass_dir=None) -> 'dict'、台帳から引くなら opsoptics.get("lens_file_read")).zmx の逐次レンズ処方を Fullseye の処方として読む(table)。
source is a file path, the file’s text, its bytes, or None for the
bundled example :data:ZMX_EXAMPLE (a Cooke triplet, f ≈ 50 mm, f/5).
Encodings: UTF-16 with a byte-order mark (what current design programs save),
UTF-16 without one (detected from the NUL pattern), UTF-8 and Latin-1.
glass_dir (or the environment variable FULLSEYE_GLASS_DIR) is a
directory of .agf glass catalogues searched before the built-in material
table. allow_partial admits the approximations listed in the module help
and marks the result approximate=True; without it they are refused.
Returns {"system", "name", "notes", "unit", "aperture", "field_type",
"fields", "wavelengths", "primary", "surfaces", "solves", "approximate",
"encoding", "source", "report"}: system is a ready
raytrace.lens_system at the primary wavelength (field 0 — pick a field
with :func:lens_file_system), fields are {"x", "y", "weight",
"field"} with field the radial value raytrace takes (degrees or mm),
surfaces is the file-level model (curvatures in 1/mm, signed thicknesses
as the file stores them, glasses, apertures, solves) that
:func:lens_file_write writes back, and report classifies every keyword
as read / ignored / unsupported (see :func:lens_file_report).
A file with an MNUM table (more than one configuration) is read into the active
configuration plus system["configurations"], a list with one sparse override dict per
configuration (see lensconfig); the result also carries n_configurations and
active_configuration (0-based).
A file with COORDBRK surfaces is read into a
raytrace3d.noncoaxial_system (noncoaxial is True, system is that
table, each field’s field is the pair (x, y), pupil holds the
entrance-pupil radius, stop radius and effective focal length found with real
axial rays, surface_records[j] the tracer records of file surface j);
the conventions are in the module help.
Example::
p = lens_file_read("triplet.zmx")
RT.paraxial_trace(p["system"])["efl"]
sysf = lens_file_system(p, field_index=2) # the 20-degree field
RT.spot_stats(sysf)
q = lens_file_read("folded.zmx") # tilts / decentres: a non-coaxial system
raytrace3d.noncoaxial_spot(lens_file_system(q, field_index=1))["rms_radius"]
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。 |
