Combined reflectance confocal microscopy-optical coherence tomography system for imaging of biological tissue
Abstract
A dual-modality apparatus for imaging of biological tissue includes a reflectance confocal microscopy (RCM) imaging apparatus and an optical coherence tomography (OCT) imaging apparatus. A first optical component reflects a first beam of light provided by a RCM imaging apparatus towards a sample and passes a second beam of light provided by an OCT imaging apparatus towards the sample, such that the first and second beam of lights share at least a portion of an imaging path.
Excerpt from the patent document:
"In some embodiments, the OCT imaging apparatus 12 is a PS-OCT imaging apparatus. In some embodiments, the OCT light source 16 is a broadband super-luminescent diode manufactured by DenseLight Semiconductors in Los Angeles, Calif. The OCT light source 16 can have a central wavelength of about 1310 nanometers and a bandwidth of about 135 nanometers. In some embodiments, the axial resolution of a broadband source (e.g. a broadband super-luminescent diode) can be determined as follows:"
