retardation_from_birefringence — OPTICS photoelastic op

使い方

複屈折 Δn から位相差 → dict(rad・nm・縞次数を並べて返す)。

retardation = t·Δn [m], delta_rad = 2π t Δn / λ, fringe_order = t Δn / λ. All three are returned so that the unit is never implicit.

Raises ValueError: a non-finite/empty Δn, |Δn| > 0.1 (no stress-induced birefringence is that large — usually a unit slip), a thickness outside [1e-7, 1] m (6 mm passed as 6) or a wavelength outside [1e-8, 2e-5] m (550 nm passed as 550).
