Ultrahigh speed and resolution OCT/OCM using broadband swept VCSEL technology
Description: This effort is expected impact public health by advancing a new clinical tool capable of three dimensional in-vivo volumetric imaging of tissue pathology without the need for tissue excision and processing as in conventional excisional biopsy and histopathology. This tool employs advanced high resolution, high data rate optical coherence tomography (OCT), which measures backscattered echoes of reflected light, in the same way that ultrasound imaging measures sound echoes, but with an imaging resolution 10-100 higher than ultrasound. The proposed instrument operates at 40X the imaging speed of existing commercial OCT instruments, and is enabled by a new compact rapidly swept laser source.
