<P>PROBLEM TO BE SOLVED: To provide a spectrum measuring device that can, despite a simple configuration, remove or reduce the influences of environmental light contained in the spectrum of an object of measurement and thereby enhance the accuracy of recognition of the object. <P>SOLUTION: A spectrum measuring device 11 recognizes an object of measurement on the basis of spectrum data S0 of observation light detected by a spectrum sensor 14 that is capable of measuring wavelength information and light intensity information. The spectrum measuring device 11 has a first recognition unit 30 dividing or subtracting, by or from the other, one of two sets of spectrum data detected at two different positions by the spectrum sensor 14 to calculate one set of correlation spectrum data correlating to the two original sets of spectrum data, and identifies at the same time the object of measurement corresponding to the two different positions on the basis of the calculated set of correlation spectrum data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
