摘要：
An optical sensor system includes a source module and a detection module. The source module includes a source housing unit having a source window member and a source shielding member. The source module emits a detection signal through the source window member. The detection module includes a detection housing unit having a detection window member and a detection shielding member. The detection module is spaced apart from the source module. The detection module detects the detection signal emitted from the source module at the detection window member.
