Isochromatic photoelastic fringe interference around gliding Volterra dislocation cores under periodic far-field shear. High stress concentration yields crystalline slip slip-lines; pristine regions relax into clean vacuum.
Between the stratified terrace beds and the Talbot wave front, the ash soil undergoes continuous far-field shear. Volterra dislocation dipoles glide along the crystalline slip bands; where the twin cores pass each other, the ground flares with transient photoelastic fringes (等色干涉条纹) before relaxing back into unpolarized vacuum.
Superposed the analytic Airy stress fields of two gliding edge dislocations with an alternating shear boundary $\tau_{xy}(t)$. The principal stress difference $|\sigma_1 - \sigma_2|$ translates cleanly to isochromatic contours: high-shear nodes resolve into structural box glyphs (║, ═, ┼), while fringe valleys settle into light stipple (░ at 52%). Dislocation transit yields a crisp motion delta of 0.594 without field blowup.
