Abstract
In part, the invention relates to a lens assembly. The lens assembly includes a micro-lens; a beam director in optical communication with the micro-lens; and a substantially transparent film. The substantially transparent film is capable of bi-directionally transmitting light, and generating a controlled amount of backscatter. In addition, the film surrounds a portion of the beam director.
Claims15
A method of calibrating an optical coherence tomography system, the method comprising:
- generating scan data in response to light reflected from a sample, the reflected light passing through a substantially transparent curved cover, the substantially transparent curved cover forming a portion of an imaging probe;
- generating reference data in response to light scattered from a plurality of back-scattering particles disposed within the substantially transparent curved cover;
- and
- calibrating the optical coherence tomography system to determine a relative position of subsequent optical coherence tomography scans in response to the reference data.
A method of calibrating an optical coherence tomography system, the method comprising:
- rotating an imaging probe having a curved cover while collecting optical coherence tomography scan data in response to light reflected from a sample, the reflected light passing through the curved cover;
- scattering light from a plurality of scattering particles disposed within the curved cover;
- generating optical coherence tomography reference data in response to scattered light reflected from a plurality of scattering particles disposed within the curved cover;
- and
- calibrating the optical coherence tomography system to determine the relative position of subsequent optical coherence tomography scans in response to the optical coherence tomography reference data.
