As for this invention, being something regarding the method of forming the fiber picture of fluorescence of the inspection body, regarding this method: The inspection body is scanned making use of the excited signal The fluorescent signal which comes from the aforementioned inspection body is detected and (the excited signal and the fluorescent signal pass by the identical optical path) Through the aforementioned optical path, two which is included in inspection internal fluorescent substances are excited at least Through the aforementioned optical path, the description above each fluorescent signal of two fluorescent substances is detected at least The last picture which includes the territory where it colors the description above according to two fluorescent substances at least is built up. The multiplex marking of this invention makes that two pictures are collected simultaneously inside two wave length zones which differ possible. The device of this invention can possess the spectrometer in order the spectrum to quantize the fluorescent signal.< Selective figure > Figure 1本発明は、検体の蛍光のファイバ画像を形成する方法に関するもので、この方法においては:励起信号を用いて検体を走査し;前記検体から来る蛍光信号を検出し(励起信号と蛍光信号は同一の光路を通る);前記光路を介して、検体内に含まれる少なくとも2つの蛍光体を励起し;前記光路を介して、前記少なくとも2つの蛍光体の各々の蛍光信号を検出し;前記少なくとも2つの蛍光体に応じて着色された領域を含む最終画像を作り上げる。本発明の多重マーキングは異なる2つの波長帯域内で2つの画像を同時に収集することを可能にする。本発明の装置は蛍光信号をスペクトル量子化するための分光計を有することができる。【選択図】 図1
