Section / setup drawing of a folded system (table, a drawing dict) — the surfaces, mirrors, beamsplitters, image plane and rays of a raytrace3d system, projected onto the meridional plane in global coordinates.
> The detailed description below is the original text — the summary and the headings are translated.
*system* は raytrace3d.noncoaxial_system の系(raytrace.lens_system の処方も受ける)。*view* は投影面:
"yz"(横軸 = 大域の z、縦軸 = y。x 軸まわりの折り返しはこの面に載る)/ "zx"(横軸 z、縦軸 x)。面は局所の子午面の sag 曲線(raytrace の円錐 + 非球面の式)を大域へ写して投影し、ガラスの群はコバの線で閉じ、鏡は裏に斜線、半透鏡は BS の印。光軸は座標系の原点の折れ線(細い一点鎖線)、絞りは口径の外の刻み、像面は像の座標系の線分(image_tilt で傾く)、有限の物体は物面の線分(object_tilt で傾く)。光線は視野ごとに色を分け、絞りの上で等間隔に絞りを狙った実光線(raytrace3d の Newton 法)。
*rotate_deg*(0 / 90 / 180 / 270)は紙の上で図を回す(同軸落射のように光が下から上へ進む装置を立てて描く)。*overlays* は別の系(例: 照明の枝 = 半透鏡で反射する系)の列で、その光線を照明の光線の層に重ねて描く(面は細線)。
寸法: 装置の占有の幅 W と高さ H(面・像面・光線の外接矩形)。注記: 光路長(第 1 面 → 像面の軸の長さ)、折り返しの角度。values: path_length / footprint / fold_angles_deg / 面ごとの大域の頂点 surfaces / 光線の大域の折れ線 rays / image_center。
Every optics op validates its input before computing (nothing slips through silently):
• Units are baked into the argument name — _mm / _um / _deg / _mrad. Confusing mm with µm does not crash; it yields a plausible-looking wrong answer, so the name prevents it. Nothing here guesses the unit from the magnitude.
• Strings raise ValueError — float('50') succeeds, so an unparsed configuration value would slip through as a length (measured: thin_lens('50', '200') returned a plausible 66.667 mm). bool is refused too, as the implicit promotion True == 1.
• complex / masked arrays raise ValueError (real-valued slots only; silently dropping the imaginary part or peeling off the mask is refused). NaN/Inf raises ValueError on every input.
• Division by zero and its relatives are refused by name: focal length 0, radius of curvature 0, refractive index <= 0, a fully opaque aperture (all zeros, so the normalisation is 0/0), a PSF whose sum is <= 0, a Stokes vector with S0 = 0, and an object sitting at the front focal point (the image is at infinity).
• Only two ops return a non-finite value, and both state it as a contract: depth_of_field returns far_mm = inf beyond the hyperfocal distance (that is what the hyperfocal distance means), and gaussian_beam returns wavefront_radius_mm = inf at the waist (the radius of curvature of a plane wavefront). Both also return a finite companion (far_is_infinite / curvature_per_mm). Any other silent NaN/Inf is detected internally and raises ValueError — "float64 overflowed" and "the answer is infinite" are different claims, so the first is never returned wearing the face of the second.
• Size caps: generated grids are capped by optics.MAX_GRID (4096); supplied fields/PSFs/apertures by optics.MAX_FIELD_ELEMENTS (2^24); ABCD element chains by optics.MAX_SYSTEM_ELEMENTS (1024); Zernike by MAX_ZERNIKE_TERMS (512) / MAX_ZERNIKE_ORDER (40) / MAX_ZERNIKE_BASIS (2^25). This closes, fail-closed, the paths where a small argument triggers a huge internal allocation (measured: n_max=40 × 4096² needs 108 GB).
• Physically impossible states are refused too: a Stokes vector with degree of polarisation > 1, negative transmittance, negative intensity, and invalid Zernike indices such as n-|m| odd.
• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).
• Operator provenance and references — the sources of the research/methods this op family came from.
• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
