查询词典 speckles

By the means of experiments and numerical simulations, it is verified that speckles can be formed when nanofluids are illuminated by laser beam. First, clear speckles are formed by illuminating static nanofluids containing proper volume fraction of nanoparticles. Then, classic-scattering-model and photon-nanoparticle-collision-model are respectively established based on the wave-particle duality of light. The formation of speckles with nanofluids is simulated respectively on these two models, and the formation mechanism of speckles is figured out.

其中通过静态实验确定激光照射含有合适体积百分比纳米粒子的纳米流体可以形成清晰的散斑图；基于光的波粒二象性，分别根据光的波动性和粒子性建立了"经典散射模型"和"光子——粒子随机碰撞模型"，基于这两个模型分别对激光照射纳米流体形成散斑的过程进行了数值模拟，并对散斑的形成机理进行了解释。

When a coherent light is scattered by the rough surface, the scatted light forms a granular intensity distribution known as speckle. Speckles are coherent superposition of the light scatted by the rough surface. Therefore, speckles carrier some information of the rough surface.

相干光从光学粗糙表面散射时，结果在探测面上出现随机的颗粒状的强度分布，称为散斑，散斑是由粗糙表面上各面元的散射光波之间的干涉在空间域内形成的，所以散斑也是粗糙表面一些信息的携带者。
