Abstract: There is provided an optical system comprising a light conduit. The light conduit comprises a first light pipe, a second light pipe, and a first bridge to mechanically couple the first light pipe to the second light pipe. The first light pipe has a first inlet to receive a first input light signal and a first outlet to emit at least a portion of the first input light signal to form a first output light signal. Moreover, the second light pipe has a second inlet to receive a second input light signal and a second outlet to emit at least a portion of the second input light signal to form a second output light signal. Furthermore, the first bridge has a first end mechanically coupled to the first light pipe and a second end mechanically coupled to the second light pipe.

Abstract: Systems, devices, and methods for detecting ambient light with wearable heads-up displays are described. An ambient light sensor can be positioned close to a user's eye area on a user-side of a wearable heads-up display. By positioning the ambient light sensor on a user-side of the wearable heads up display, the ambient light sensor can be in a position and/or orientation which receives ambient light in a similar manner a user's eye, and thus ambient light detection can be more accurate. Brightness of display light output by the wearable heads-up display can be adjusted in response to the detected brightness of ambient light.
