| 英文摘要 | An optical transducer includes a light-emitting device with a light output that has an angular spatial intensity distribution exhibiting multiple peaks. A lens is closely coupled to the light-emitting device to reduce the angular spread of the spatial intensity distribution, preferably to a single peak on the optical axis. The lens is preferably a ball lens coupled to the light-emitting device by a refractive glue. |
