Abstract
In part, the invention relates to a single clad fiber to multi-clad optical fiber connector for use in applying excitation light to a sample and obtaining reflected light from the sample. The connector can include a dual clad optical fiber portion and a single clad optical fiber portion in optical communication with the dual clad optical fiber portion. In one embodiment, a core of the dual clad optical fiber portion and a core of the single clad optical fiber portion have substantially similar indices of refraction. In one embodiment, excitation light is propagated by the core of the dual clad optical fiber. Further, in one embodiment, light reflected by the sample is propagated by the first cladding layer of the dual clad optical fiber portion.
Claims8
A method of collecting optical coherence data and spectroscopic data from a sample comprising the steps of:
- transmitting light in an optical fiber core having a first index of refraction to the sample;
- receiving light scattered from the sample;
- transmitting scattered light from the sample having a first mode in the optical fiber core to a first detector;
- transmitting scattered light from the sample having a second mode in a first cladding layer having a second index of refraction to a second detector;
- generating an optical coherence tomography image using the scattered light from the sample having the first mode;
- and
- overlaying spectroscopic data on the optical coherence tomography image, the spectrographic data obtained using the scattered light from the sample having the second mode.
A method of collecting optical coherence data and spectroscopic data from a sample comprising:
- transmitting light along a first optical fiber core to the sample;
- receiving light scattered from the sample at a second optical fiber core and an inner cladding, wherein the second optical fiber core and the inner cladding are concentrically arranged;
- transmitting scattered light from the sample having a first mode from the first optical fiber core to a first detector,
- transmitting scattered light from the sample having a second mode to a second detector;
- and
- generating an optical coherence tomography image of the sample having spectroscopic data overlaid thereon using the scattered light having the first mode and the scattered light having the second mode.
