Skin phantoms are often used to study and model light propagation. However, existing skin phantoms overlook the important effect of surface roughness on light propagation patterns. This paper reports the construction of durable phantoms with controllable surface roughness and bulk optical properties. With silica microspheres as the scattering particles, we theoretically model the scatterer density required to achieve the desired phantom optical properties before fabrication. The surface roughness and the attenuation coefficients of the constructed phantoms were validated using optical profilometry and ballistic spatial filter photometry. These rough skin phantoms were originally developed for laser speckle studies, but could also be used for studying optical phenomena where light experiences surface and bulk scattering at the same time.
皮肤仿体常用于研究和模拟光传播。然而，现有的皮肤仿体忽略了表面粗糙度对光传播模式的重要影响。本文报告了具有可控表面粗糙度和体光学性质的耐用仿体的构建。我们使用二氧化硅微球作为散射粒子，在制造之前从理论上模拟了实现所需仿体光学性质所需的散射体密度。使用光学轮廓仪和弹道空间滤波器光度法验证了所构建的仿体的表面粗糙度和衰减系数。这些粗糙皮肤仿体最初是为激光散斑研究开发的，但也可用于研究同时经历表面和体散射的光学现象。
