1. An optical device, comprising a galvanometer assembly, a bottom plate, and at least one optical transceiver component,
wherein the at least one optical transceiver component comprises a first optical transceiver component and a second optical transceiver component, each optical transceiver component comprises an emitting assembly and a receiving assembly;
wherein the emitting assembly of the first optical transceiver component is configured to emit a first outgoing light signal along a first optical axis to a detection region and the receiving assembly of the first optical transceiver component is configured to receive a first reflected light signal along the first optical axis returning from the detection region;
wherein the emitting assembly of the second optical transceiver component is configured to emit a second outgoing light signal along a second optical axis to the detection region and the receiving assembly of the second optical transceiver component is configured to receive a second reflected light signal along the second optical axis returning from the detection region;
wherein the galvanometer assembly is configured to receive the first outgoing light signal and the second outgoing light signal from the first optical transceiver component and the second optical transceiver component, respectively, and direct the first reflected light signal and the second reflected light signal to the first optical transceiver component and the second optical transceiver component, respectively;
wherein the bottom plate is configured to secure relative positions of the first optical transceiver component, the second optical transceiver component, and the galvanometer assembly;
wherein each optical transceiver component further comprises a secondary beamsplitter; and
wherein the secondary beamsplitter of the first optical transceiver component is configured to filter out S-polarized light signal from the first outgoing light signal; and the secondary beamsplitter of the second optical transceiver component is configured to filter out S-polarized light signal from the second outgoing light signal.
