The goal of this work was to develop a probe that minimizes such artifacts.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>Our probe was fabricated using a single mode fiber at the tip of which a glass spacer and graded index objective lens were spliced to achieve the desired focal distance. The signal was reflected using a curved reflector to correct for astigmatism caused by the thin, protective, transparent sheath that surrounds the optics. The probe design was optimized using Zemax, a commercially available optical design software. Common path interferometric operation was achieved using Fresnel reflection from the tip of the focusing graded index objective lens. The performance of the probe was tested using a custom designed spectrometer\u2010based OCT system.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The probe achieved an axial resolution of 15.6\u2009\u03bcm in air, a lateral resolution 33\u2009\u03bcm, and a sensitivity of 103\u2009dB. A scattering tissue phantom was imaged to test the performance of the probe for astigmatism correction. Images of the phantom confirmed that this common\u2010path, astigmatism\u2010corrected OCT imaging probe had minimal artifacts in the axial, and lateral dimensions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In this work, we developed an astigmatism\u2010corrected, common path probe that minimizes artifacts associated with standard OCT probes. This design may be useful for OCT applications that require high axial and lateral resolutions. Lasers Surg.
