Abstract
An apparatus to interrogate, receive, and analyze full emission spectra for at least one fluorescence excitation wavelength and for at least one reflectance measurement to determine tissue characteristics. The apparatus includes a base unit having illumination, detection and control sub-units, the illumination sub-unit providing illumination optical energy for illuminating a target tissue and the detection sub-unit detecting tissue characteristics of a target tissue, a separate tissue interface unit, and a pathway coupling the base unit and the tissue interface unit. The system and apparatus may also include a tube for maintaining the distance between the tissue and units and for surrounding the tissue to prevent patient movement from being transmitted to the tissue.
