Assignee: LUNA INNOVATIONS INCORPORATED
Field: Measurement (Instruments)
Classification: CPC G  H | IPC H

Claim 16:
17. The optical apparatus in claim 16, wherein the optical apparatus includes an optical vector analysis network comprising:
a launch conditioning network, coupled to the light source, including a first light path and a second light path, where the second light path is delayed with respect to the first light path, and a polarization controller to ensure light in the first light path is substantially orthogonal to light in the second light path; and
a measurement interferometer to combine the light from first and second paths in the launch conditioning network with light reflected from the waveguide,
wherein the optical detection circuitry includes a polarization diverse receiver, coupled to the measurement interferometer, to separately detect the first polarization state back scatter data and the second polarization state back scatter data.
