Lenticular Cross-Talk — first-order model

2-view interleaved lenticular array. Cross-talk = ratio of wrong/correct view luminance at the eye. Not a substitute for photometry.

Model: thin lens, paraxial. View profile = active sub-pixel width convolved with Gaussian σ=√(σ_diff²+σ_aberr²), σ_diff≈0.38·λ·D/P, λ=550 nm, plus a broad Lorentzian halo (spherical aberration + oblique emission + panel black) set by the aberration/tail control, plus a uniform haze floor. Yaw puts each eye at its own distance and lateral position. This is an optimistic first-order estimate, not a measurement — set aberration/tail 0 and haze 0 to see the pure geometric floor. Ground truth is photometry: CT=(L_leak−L_k)/(L_w−L_k).
