Title:

LIGHT IRRADIATION APPARATUS

Document Type and Number:

WIPO Patent Application WO/2008/018270

Kind Code:

A1

Abstract:

A light irradiation apparatus (1) is provided with a laser light source (10) for generating laser light; a light source (20) for detection light, for generating detection light having a prescribed wavelength; an optical fiber (30), which permits the laser light to be inputted from one end surface (30a) and to be outputted from the other end surface (30b) to irradiate an object (3), permits the detection light to be inputted from the end surface (30a), and has an FBG (32) in the vicinity of the end surface (30b) for reflecting light having a prescribed wavelength; a light detector (50) for detecting intensity of detection light, which is reflected by the FBG (32) and outputted from the end surface (30a); and a signal processing section (60) for detecting irradiation status of the object (3) with the laser light, based on the detected intensity of the detection light. The laser light generated from the laser light source (10) has a wavelength other than that reflected by the FBG (32).
