光束与物质的相互作用显示出对横向运动的极端敏感性。通过一族新的衍射图，揭示了相互作用和光致微扰的扩散输运的时空离域。在二级相变点附近，介质对光的横向运动的响应增强。这一现象在研究基于多普勒效应的方法所不能及的运动方面具有很大的应用潜力，并提出了具有非平稳影响的临界过程的基本问题。
Interaction of a light beam with matter reveals extreme sensitivity to transverse motions. Spatio-temporal delocalization of interaction and diffusive transport of light-induced perturbations is revealed through a new family of diffraction patterns. The response of the medium to the transverse motion of the light enhances near the second order phase transition point. The phenomenon has large application potential for the study of motions that are beyond the power of Doppler-effect-based methods, and suggests fundamental problems about critical processes with nonstationary influences.
