Abstract:
1. A medical device, comprising: a first light source for emitting a first light signal operating in a first region of the light spectrum that enables visualization of a target tissue; a second light source for emitting a second light signal operating in a second region of the light spectrum that enables a reflection of a portion of the second light signal from at least one subsurface of the target tissue; a first optical device providing a coaxial optical path of the first light signal and the second light signal, wherein a relative position of the first optical device to the first and second light sources further provide a first focal point of the first light signal to be in at least a proximate location of a second focal point of the second light signal; and a second optical device to adjust the first focal point of the first light signal without changing the at least proximate location of the first focal point relative to the second focal point of the second light signal.
