摘要
Angle-resolved low-coherence interferometry (a/LCI) detects precancer by enabling depth-resolved measurements of nuclear morphology in vivo. A significant limitation of a/LCI is the point-probe nature of the method, sampling <0.5 mm(2) before probe relocation is necessary. In this work, we demonstrate a scanning method capable of assessing an area > 100 mm(2) without repositioning. By utilizing a reflection-only three-optic rotator prism and a two-axis scanning mirror, we demonstrate radial scans of a sample with a linear range of 12 mm and a full rotational range of 180 degrees. Use of this design will improve the diagnostic utility of a/LCI for wide-area screening of tissue health.
