Abstract
A method and apparatus for imaging using a double-clad fiber is described.
Claims6
A method for imaging a sample through an optical fiber having at least one first cladding region and at least one second cladding region, comprising:
- transmitting a first propagating light through the at least one first cladding region of the optical fiber toward the sample;
- and
- collecting a scattered light from the sample in the at least one second cladding region.
An apparatus, comprising:
- a light transmission path arrangement which includes at least one of an optical fiber and an optical waveguide, the light transmission path arrangement illuminating a sample with a beam of light, the light transmission path arrangement including at least one first cladding region;
- and
- a light collection path arrangement which is separate from the light transmission path arrangement, the light collection path arrangement including a fiber core and at least one second cladding region receiving light reflected from the sample.
