Abstract:
1. A probe using integrated confocal reflectance imaging, confocal Raman spectroscopy, and gross spatial imaging for non-invasively evaluating a target of interest of a living subject, comprising: (a) a casing with a first end and an opposite, second end; (b) a first optical port, a second optical port, and a third optical port, wherein the first and second optical ports are located at the first end of the casing and the third optical port is located at the second end of the casing such that the first and third optical ports define a first optical path therebetween, and the second and third optical ports define a second optical path therebetween, respectively, wherein each of the first and second optical paths has a first portion and a second portion, and wherein the second portions of the first and second optical paths are substantially overlapped and proximal to the third optical port; (c) a collimation lens, a coupling lens, and an objective lens assembly; (d) a first mirror, a second mirror, and a third mirror; (e) a band pass filter; (f) a long pass filter; (g) a scanning member; (h) an electronic imaging device; and (i) a focus control device, wherein the collimation lens, the band pass filter, and the second mirror are placed at the first portion of the first optical path, the coupling lens, the long pass filter and the first mirror are placed at the first portion of the second optical path, and wherein the third mirrors, the scanning member, and the objective assembly are placed at the overlapped second portion of the first and second optical paths.
