PROBLEM TO BE SOLVED: To monitor the incident situations of the rays of light to the output optical fibers without impairing the rays of light which are made incident on the output optical fibers from an inverse dispersion double spectroscope.;SOLUTION: The 1st order diffracted light λ12 of the rays of light which has passed a grating 12 with light λ2 from a beam steering mechanism 15 is made incident on one of optical fibers 1 to 8 for output through a magnifying optical system 11. On the other hand, 0 order diffracted light λ02 different from the 1st order diffracted light λ12 of the rays of light which has passed the grating 12 is made incident on an output place monitoring device 200. The output place monitoring device 200 is equipped with a photo sensor 24 for output place detection which is arranged in a position which is shifted from a conjugate position with the reflecting surface of the micro-mirror of the beam steering mechanism 15. The device 200 recognizes the output place of the 1st order diffracted light λ12 by which position of the the sensor 24 the 0 order diffracted light λ02 is received.;COPYRIGHT: (C)2005,JPO&NCIPI
