Abstract
This application provides an optical device, including an emitting assembly configured to emit an outgoing light signal, a beam splitting assembly configured to pass the outgoing light signal from the emitting assembly to a detection region, receive a reflected light signal from the detection region, and modify a transmission direction of the reflected light signal, a receiving assembly configured to receive the reflected light signal from the beam splitting assembly after the direction modification and generate an electrical signal in response to the reflected light signal. Also disclosed is a method of adjusting an optical device as described herein.
Claims21
An optical device, comprising:
- an emitting assembly configured to emit an outgoing light signal;
- a beam splitting assembly configured to pass the outgoing light signal from the emitting assembly to a detection region, receive a reflected light signal from the detection region, and modify a transmission direction of the reflected light signal, wherein the reflected light signal comprises at least a part of the outgoing light signal reflected by an object in the detection region;
- and
- a receiving assembly configured to receive the reflected light signal from the beam splitting assembly after the direction modification and generate an electrical signal in response to the reflected light signal.
An optical device, comprising:
- a first optical transceiver component configured to emit a first outgoing light signal along a first optical axis to a detection region and receive a first reflected light signal along the first optical axis returning from the detection region;
- a second optical transceiver component configured to emit a second outgoing light signal along a second optical axis to the detection region and receive a second reflected light along the second optical signal axis returning from the detection region;
- a galvanometer assembly 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;
- and
- a bottom plate configured to secure relative positions of the first optical transceiver component, the second optical transceiver component, and the galvanometer assembly.
A method for adjusting an optical device, comprising:
- aligning an emitting assembly and a beam splitting assembly;
- coupling a receiving assembly to the beam splitting assembly;
- emitting, by the emitting assembly, an outgoing light signal to a detection region through the beam splitting assembly along a first transmission direction, wherein the beam splitting assembly receives a reflected light signal from the detection region and direct the reflected light signal along a second transmission direction to the receiving assembly, the reflected light signal comprising at least a part of the outgoing light signal reflected from the detection region;
- detecting the reflected light signal directed from the beam splitting assembly to the receiving assembly;
- comparing the reflected light signal with a threshold value;
- and
- adjusting the optical transceiver component until the reflected light signal received by the receiving assembly is greater than or equal to the threshold value.
