Orientated acquisition device of incident light and manufacturing method of orientated acquisition device

The invention provides an orientated acquisition device of incident light and a manufacturing method of the orientated acquisition device. By setting a top light reflecting assembly and a slope light reflecting assembly, and installing light reflection mirrors in different angles on the slope light reflecting assembly, incident light in four different directions can be selected, and incident light in a specific incident angle range can be controlled to irradiate a light sensor, so selection of the incident light by the light sensor is achieved and mis-judgments are reduced. 本发明提供入射光线定向采集装置及其制造方法，通过设置顶部反光组件、斜面反光组件，在斜面反光组件上安装不同角度的反光镜以选择四个不同方向的入射光线，并且可以控制特定入射角范围的入射光线落到光线传感器上，实现了光线传感器对入射光线的选择，降低误判。
