We report on the initial results of the first automated classifier to distinguish basal cell carcinomas and healthy skin using polarization sensitive optical coherence tomography (PS-OCT) with a sensitivity and specificity of 84.2% and 85.8%.
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 optical coherence tomography has the potential to achieve accurate diagnosis of skin cancer noninvasively.
From liquid mirrors in telescopes to liquid lenses in camera phones, systems with optical interfaces formed between two fluids possess unique characteristics. This talk focuses on optofluidic devices based on liquid-liquid interfaces in microfluidic systems.
An ultrasensitive nonlinear cavity sensing method is proposed and demonstrated, in which the detection limit is not bounded by the quality factor of the cavity. 10mg/dL glucose concentration and 100aM BSA molecules are detected.
This work presents the photoinduced wavelength shift of a side-polished fiber Bragg grating (SPFBG) with a photoresponsive liquid crystal (LC) overlay. The reflection peak wavelength of the SPFBG is tuned by refractive index (RI) modulation, which comes from the phase transition of the overlaid photoresponsive LC under ultraviolet (UV) light irradiation. The wavelength shift of 0.66 nm is observed...
A new scheme for adaptive optical power equalization in passive optical networks is proposed based on dynamic gain control of semiconductor optical amplifiers. Because of this new scheme, continuous-mode receiver front-end can be used for upstream burst-mode transmission. Experimental testbed is demonstrated with -31dBm receiver sensitivity and >34dB dynamic range using continuous-mode receiver...
