Stereoscopic beam splitter
View Patent ↗According to certain embodiments, a system includes beamsplitter sets, where each beamsplitter set comprises a first beamsplitter module and a second beamsplitter module aligned with the first beamsplitter module. The first beamsplitter module receives a first beam traveling along a first optical path. The first beamsplitter module splits the first beam into a first output beam transmitted along the first optical path and a first split beam transmitted to the second beamsplitter module along a reflected beam path. The second beamsplitter module receives the first split beam. The second beamsplitter module splits the first split beam into a second output beam transmitted substantially parallel to the reflected beam path and a second split beam transmitted substantially perpendicular to the reflected beam path.
1. A system comprising:
a plurality of beamsplitter sets, each beamsplitter set comprising a first beamsplitter module and a second beamsplitter module aligned with the first beamsplitter module:
the first beamsplitter module configured to:
receive a first beam traveling along a first optical path; and
split the first beam into a first output beam transmitted along the first optical path and a first split beam transmitted to the second beamsplitter module along a reflected beam path;
the second beamsplitter module configured to:
receive the first split beam and transmit the first split beam substantially parallel to the reflected beam path line; and
receive a second beam and transmit the second beam to the first beamsplitter module; and
the first beamsplitter module further configured to:
receive the second beam and transmit the second beam along the first optical path.
2. The system of claim 1 , the beamsplitter modules of the beamsplitter sets being aligned.
3. The system of claim 1 , the first beamsplitter module configured to receive the first beam from an objective lens.
4. The system of claim 1 , the first beamsplitter module configured to send the first output beam to one or more eyepieces.
5. The system of claim 1 , the second beamsplitter module configured to send the first split beam to a port.
6. The system of claim 1 , the second beamsplitter module configured to receive the second beam from an image display system.
7. A method comprising:
receiving a plurality of light beams at a plurality of beamsplitter sets, each beamsplitter set comprising a first beamsplitter module and a second beamsplitter module aligned with the first beamsplitter module;
receiving, at the first beamsplitter module, a first beam traveling along a first optical path;
splitting, by the first beamsplitter module, the first beam into a first output beam transmitted along the first optical path and a first split beam transmitted to the second beamsplitter module along a reflected beam path;
transmitting, by the second beamsplitter module, the first split beam substantially parallel to the reflected beam path line;
transmitting, by the second beamsplitter module, a second beam to the first beamsplitter module; and
transmitting, by the first beamsplitter module, the second beam along the first optical path.
8. The method of claim 7 , further comprising:
receiving, at the first beamsplitter module, the first beam from an objective lens.
9. The method of claim 7 , further comprising:
sending, by the first beamsplitter module, the first output beam to one or more eyepieces.
10. The method of claim 7 , further comprising:
sending, by the second beamsplitter module, the first split beam to a port.
11. The method of claim 7 , further comprising:
receiving, at the second beamsplitter module, the second beam from an image display system.
