Abstract
An optical comb measuring apparatus that measures an irradiation target having multiple types of measuring targets, includes: an interference signal acquiring section; and a frequency spectrum measuring section. The interference signal acquiring section acquires an interference signal between a post-irradiation signal comb obtained by irradiating the irradiation target with a pre-irradiation signal comb and a local comb set to be different from a repetition frequency of the pre-irradiation signal comb by a predetermined differential frequency. The frequency spectrum measuring section measures a frequency spectrum of a result of acquisition by the interference signal acquiring section. Either one or both of the post-irradiation signal comb and the local comb provided to the interference signal acquiring section have only components within a plurality of required bands including all of predetermined frequencies. Frequency bands of the interference signal corresponding to the plurality of respective required bands have no areas overlapping each other.
