Abstract
A particle detecting device includes: a fluorescence measuring instrument that measures light in a fluorescent band, which is produced in a region that is illuminated by an excitation beam from a light source; and an evaluating portion that evaluates whether the light measured by the fluorescence measuring instrument includes Raman-scattered light and florescent light, to evaluate that a fluorescent particle is included in the fluid if the evaluation is that the measured light includes florescent light, and to evaluate that the fluid does not include a fluorescent particle if the evaluation is that the measured light does not include fluorescent light, to evaluate that moisture is included in the fluid if there is an evaluation that the measured light includes Raman scattered light, and to evaluate that the fluid does not include moisture if there is an evaluation that the measured light does not include Raman scattered light.
