1. A light therapy diagnostic device comprising:
a shaft having a distal end and a proximal end in a longitudinal direction and a lumen extending in the longitudinal direction; and
an optical waveguide disposed in the lumen of the shaft such that the optical waveguide is movable forward and backward in the longitudinal direction; wherein:
the optical waveguide guides a first light and a second light;
the shaft has a lateral emission window located on a lateral part of the shaft and a distal emission window located on a distal end part of the shaft;
the lateral emission window is configured to allow the first light and the second light to be emitted from the optical waveguide toward a lateral direction;
the distal emission window is configured to allow the first light to be emitted from the optical waveguide toward a distal direction;
a first mirror is provided on a distal end part of the optical waveguide such that the first mirror reflects the first light toward a lateral direction of the shaft; and
a second mirror is provided on an inner surface of the shaft, located distal to a distal end of the lateral emission window, such that the second mirror reflects the first light reflected by the first mirror toward the distal end of the shaft.
