Patent ID: 8711336

Claim:
A photonic Doppler velocimetry probe comprising a housing defining an interior space between a first end and a second end; one or more optic signal conductors entering the housing through the second end a terminating end within the interior space of the housing, the one or more optic signal conductors configured to provide one or more optic signals to one or more lenses in the probe, the probe configured for velocimetry measurements; a ferrule, located within the housing, having one or more passages configured to receive and secure at least one of the one or more optic signal conductors to the ferrule; an index-matching lens having a flat surface adjacent the ferrule to receive the optic signal, the index-matching lens having an index of refraction selected to match an index of refraction of the one or more optic signal conductors; a fish eye lens, mounted at the first end, configured to receive the optic signal and project the optic signal outward in a direction controlled by the configuration of the fish eye lens.
