1) Because the light induced by the electric discharge of the Argon laser oscillator intermingles with an emission spectrum, it is necessary to eliminate it by interposing a suitable band pass filter between a laser oscillator and a fiber for laser irradiation.
2) The almost same emission spectrum is obtained when the coaxial optical fiber is placed in a vertical position to the material and for a distance of 0 to 2mm between its tip and the material.
3) The emission spectra are almost similar which are measured for three consecutive times in close contact with a same point of the resected,non-fixed gastric mucosa, and its noise is considerably eliminated by integrating them.
4) The difference of the fluorescent intensity between two points is never significant unless it is 30% and more.
5) The emission spectrum measured through the broken optical fibers for detection is intermingled with other light besides ture emission.
