摘要	A light source module adapted to provide a superposition structured pattern includes a light emitting device adapted to provide a light beam, a light guiding element including a polarizing beam splitter to separate the light beam into a first light beam and a second light beam, a first diffractive element configured to convert the first light beam into a first structured light, and a second diffractive element configured to convert the second light beam into a second structured light. Polarization states of the first light beam and the second light beam are different. The first and second structured lights are projected into a projection region, and overlapped and imaged as a superposition structured pattern. The projection region has sub-projection regions arranged in a matrix and adjacent to each other, and the pattern distribution of the superposition structured pattern in each sub-projection region is different from each other.
其他摘要	一种适于提供叠加结构图案的光源模块，包括：一种适于提供光束的发光装置；一种光导元件，其包括用于将光束分离为第一光束和第二光束的偏振分束器；衍射元件，被配置为将第一光束转换为第一结构光，第二衍射元件，被配置为将第二光束转换为第二结构光。第一光束和第二光束的偏振状态不同。第一和第二结构化光被投影到投影区域中，并且被重叠并成像为叠加结构化图案。投影区域具有布置成矩阵并且彼此相邻的子投影区域，并且在每个子投影区域中的重叠结构化图案的图案分布彼此不同。
