Abstract

A beam combiner is configured to generate a combined image by combining a first image and a second image, and transmit the combined image to a user. One or more light pipes are coupled to the beam combiner from one or more indicator lights. Each light pipe is configured to receive light from a respective indicator light and transmit the light from the respective indicator light to the beam combiner, which is then seen by the user.

Claims (31)

1. A beam combiner assembly comprising: a beam combiner configured to generate a combined image by combining a first image from a first imager and a second image from a second imager, the beam combiner further configured to transmit the combined image onto a display to a user; at least one indicator light, including an LED, mounted on a surface for visually alerting the user of an operating status of either the first imager or the second imager, wherein when the at least one indicator light is ON, a visual alert as rays of light is provided to the user directly from the at least one indicator light; one or more light pipes, configured as individual waveguides for moving rays of light from one location to another location, positioned between the at least one indicator light and the beam combiner, wherein each light pipe is configured to receive the visual alert as rays of light from a respective indicator light and transmit the visual alert as rays of light to the beam combiner for further transmission of the visual alert onto the display to the user; wherein each light pipe is configured to receive light from a respective indicator light, and each light pipe is configured to transmit the light from the respective indicator light to the beam combiner.

2. The beam combiner assembly of claim 1 , wherein

the beam combiner is configured to transmit the combined image to a user through an axial surface of the beam combiner, and

the one or more light pipes are configured to transmit the light to a radial surface of the beam combiner.

3. The beam combiner assembly of claim 1 , wherein

the one or more light pipes are configured to transmit the light such that the indicators are visible at a perimeter of the combined image transmitted by the beam combiner.

4. The beam combiner assembly of claim 1 , wherein

the one or more light pipes transmit the light to the beam combiner in a substantially circumferential direction.

5. The beam combiner assembly of claim 1 , wherein

the one or more light pipes are configured to transmit the light such that the indicators are visible outside of the combined image transmitted by the beam combiner.

6. The beam combiner assembly of claim 1 , wherein

the one or more light pipes transmit the light to the beam combiner in a substantially radial direction.

7. The beam combiner assembly of claim 1 , wherein

the one or more light pipes are configured to transmit the light such that the light diffuses throughout at least a portion of the combined image transmitted by the beam combiner.

8. The beam combiner assembly of claim 1 , wherein

the one or more light pipes are configured to transmit the light such that the light is focused at a single point in the combined image transmitted by the beam combiner.

9. The beam combiner assembly of claim 1 , further comprising:

a user optical output,

wherein the beam combiner is configured to transmit the combined image to the user optical output, and

the user optical output is configured to focus the combined image and transmit the combined image to the user.

10. The beam combiner assembly of claim 1 , further comprising a frame configured to hold the beam combiner, wherein

the one or more light pipes are mounted to the frame.

11. The beam combiner assembly of claim 10 , further comprising:

a display configured to generate the second image and transmit the second image to the beam combiner, the display including a display connector slot; and

a display connector adapted to couple to the display connector slot of the display, the display connector including the one or more indicator lights.

12. The beam combiner assembly of claim 11 , wherein

the frame includes a mounting portion, and

the display connector mounts to the mounting portion of the frame when the display connector is coupled to the display.

13. The beam combiner assembly of claim 12 , wherein

the mounting portion comprises snap arms.

14. The beam combiner assembly of claim 1 , wherein each light pipe is configured to receive all of the light from the respective indicator light when the display connector is coupled to the display.
