acoustic_material_table — ACOUSTICS ultrasonic op

• Data kinds: none → table (an op determined by its arguments alone — it takes no image or data input)

• Call: import fullseye as fs; fs.ledger.acoustic_material_table() (to call the implementation directly, import ultrasound; ultrasound.acoustic_material_table(); from the registry, opsacoustics.get("acoustic_material_table"))

Usage

Built-in acoustic material table: density, longitudinal speed, impedance Z = rho*c, attenuation alpha0*f^n, with a source and a verified flag per entry (table).

> The detailed description below is the original text — the summary and the headings are translated.

返り: {"kind": "acoustic_materials", "materials": {name: {rho, c, Z, alpha0, alpha_n, verified, source, uncertainty}}}。verified が False の材料は代表値の置き場で、acoustic_layer_stack は allow_unverified=True が無い限り拒む。

単位: rho [kg/m³]、c [m/s]、Z [Rayl]、alpha0 [Np/m/Hz^n]。

Raises: 何も拒まない(引数が無い)。返す dict は毎回の複製で、書き換えても表は変わらない。

• 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.
