Image of FIG. 1.
FIG. 1.

Schematic diagram of common-path interferometer based OCT system. SLD is the broadband light source, C1 is the circulator, D1 is the detector, and L1 and L2 are the path lengths of the two arms of the scanning interferometer (Ref. 12).

Image of FIG. 2.
FIG. 2.

Schematic diagram of the angle cleaved bare fiber probe.

Image of FIG. 3.
FIG. 3.

The ratio of reference and incident power as a function of the angle of cleaved fiber probe.

Image of FIG. 4.
FIG. 4.

Experimental setup for circumferential scanning of the hollow artery using just bare fiber probe.

Image of FIG. 5.
FIG. 5.

Modified probe experimental setup: Lateral scanning by using the side-viewing fiber probe in series with an AR coated lens to obtain cross-sectional images of the hollow artery.

Image of FIG. 6.
FIG. 6.

OCT image obtained by circumferential scanning over 90° sector of the artery. The bare fiber angle cleaved probe was used as described by the experimental setup in Fig. 4.

Image of FIG. 7.
FIG. 7.

Cross-sectional image of the artery using the angle cleaved fiber in series with an external lens.

Image of FIG. 8.
FIG. 8.

An improved OCT image of the onion sample using the experimental setup described in Fig. 5.
