Abstract:
1. A transmission module, comprising: a first control device emitting a first light or receiving a first reflected light; a second control device emitting a second light when the first control device emits the first light and receiving a second reflected light when the first control device receives the first reflected light; a first reflection device disposed opposing the first control device and having a first scope of mapping, wherein the first scope covers the first control device; and a second reflection device disposed opposing the second control device and having a second scope of mapping, wherein the second first scope covers the second control device, wherein when the first control device emits the first light, the first reflection device reflects the first light to generate a third light, and when the second control device emits the second light, the second reflection device reflects the second light to generate a fourth light, and wherein the transmission module further comprises an isolation device disposed between the first and the second reflection devices to prevent the second light from being affected by the third light and prevent the first light from being affected by the fourth light.
