<p>An optoelectronic module (130, 148) includes a beam transmitter (104), which emits at least one beam of light along a beam axis, and a receiver (114), which senses the light received by the module along a collection axis of the receiver, which is parallel to the beam axis within the module. Beam-combining optics (142, 150, 170) direct the beam and the received light so that the beam axis is aligned with the collection axis outside the module. The beam-combining optics include multiple faces, including at least a first face (144, 160, 172) configured for internal reflection and a second face (146, 151) comprising a beamsplitter (158), which is intercepted by both the beam axis and the collection axis.</p> |
