Fluorescent spectral analysis apparatus

摘要

A fluorescent spectral analysis apparatus comprises a source of a laser beam, and first and second optical fibers to be inserted in an endoscope with forward ends extended from a distal end of the endoscope. The first optical fiber guides the laser beam emitted from the source to a subject portion to be analyzed and the second optical fiber transmits a fluorescent light generated from the subject portion due to irradiation with the laser beam. The fluorescent light is detected by a light-receiving element. The time interval between the instant of reception of the fluorescent light by the light receiver and the instant of generation of the laser beam from the source is measured.
