Abstract
A floating particle detection deviceis capable of accurately identifying the type of a floating particle while achieving simplification of a configuration of the device, the device includes: a laser light irradiator () that includes a laser light emitting element () and a back-monitor-use light receiving element (); a scattered light receiver () that selectively receives light of a predetermined polarization component among scattered light generated when a floating particle () is irradiated and that generates a second detection signal; and an identification processor () that identifies the type of the floating particle on the basis of a first detection signal and the second detection signal. Incident light entering the back-monitor-use light receiving element () includes: a back-monitor-use laser beam (L); and backscattered light (Lbs) travelling toward the laser light irradiator () among the scattered light (Ls).
