International audience; We demonstrate the first application of the differential depolarization index (DDI) for depolarization imaging in polarization-sensitive optical coherence tomography (PS-OCT). Unlike the widely used degree of polarization unif

Publikováno v: Biomedical Optics 2016.

We report results on the first automated detection of basal cell carcinoma in human skin using polarization-sensitive optical coherence tomography. Our classifier achieves a sensitivity, specificity and accuracy of 92.6%, 87% and 90%, respectively.

We demonstrate the first system for optical coherence tomography (OCT) that enables simultaneous measurement of quantitative birefringence and strain in biological samples using a common-path configuration. Owing to its superior phase stability, comm

Automated classification of basal cell carcinoma in mouse skin by polarization sensitive optical coherence tomography

Publikováno v: CLEO: 2014.

An automated, support-vector-machine classifier was developed to discriminate basal cell carcinoma from healthy mouse skin images obtained with polarization sensitive optical coherence tomography. The results demonstrate that polarization sensitive o

High-resolution spectrometer: solution to the axial resolution and ranging depth trade-off of SD-OCT

Autor: Audrey K. Ellerbee, Hee Yoon Lee, Tahereh Marvdashti

Publikováno v: SPIE Proceedings.

We demonstrate a cross-dispersed spectrometer for Spectral Domain Optical Coherence Tomography (SD-OCT). The resolution of a conventional SD-OCT spectrometer is limited by the available sizes of the linear array detectors. The adverse consequences of
