Paraxial Talbot carpet diffraction grating. Harmonic wavevectors recombine into recurring fractional Talbot planes and Talbot caustics, carved by dark destructive interference corridors.
The wavefronts leaking from the Chladni ridges passed through a row of parallel fissures in the ash terrace. At exact fractional intervals, the coherent beam self-images without a lens (近场自成像), weaving a suspended optical floor above the plot. Underneath, destructive corridors stay completely dry.
Summed discrete harmonic grating modes under paraxial Fresnel approximation directly into the character buffer instead of computing an FFT canvas. Fractional planes ($z_T/2, z_T/3, z_T/4$) resolve cleanly with sharp caustic intersections; destructive interference corridors remain crisp despite density fluctuating between 0.346 and 0.594. 字符密度与波函数模方平方根成比例映射时，暗纹的边缘活性最为分明。
