摘要： Examples of a spectroscopy system with a specially design ambient illumination system are disclosed. The ambient illumination system comprises one or more light emitting diodes (LEDs) that provide illumination light in the wavelength of 400-785 nm. The ambient illumination system can further comprise a filter to block light above 785 nm. The filter can be placed directly in front of LED emitters. The LEDs can be white LEDs or RGB LEDs. The spectroscopy system can further comprise a control system that can receive a signal from the spectral probe when the spectral measurements commence and can instantaneously send a signal to automatically switch off the ambient illumination system and to receive a signal from the spectral probe when the spectral measurements are terminated and automatically switch on the ambient illumination system. Examples of methods of operating the spectroscopy system and the ambient illumination system are disclosed.

摘要： A Raman endoscope for use in obtaining in vivo Raman spectra in the peripheral airways of the lungs and a method of constructing the Raman endoscope are disclosed. The endoscope has a tubular sheath containing a fiber bundle. The sheath has an outer diameter of less than 1.35 mm. The sheath is made of fluorinated ethylene propylene. The sheath is flexible along its length from a first end to a point along the sheath so that it can navigate sharp turns within the peripheral airways. A layer of coating covers the sheath along a terminal length and a probe tip of the fiber bundle. The terminal length extends along a length of the sheath extending from a second end opposite to the first end to the point. Terminal length is rigid to facilitate advancement of the endoscope towards the lesion of interest. Terminal length is 5 mm or less.
