| 发明名称 | Optical wavelength meter | ||
| 摘要 | An optical wavelength meter includes: an interferometer; a reference optical source unit with a laser configured to oscillate in a multi-longitudinal mode; and a signal processor configured to calculate a wavelength of a input beam with reference to interference fringe information of reference beam and interference fringe information of the input beam obtained from the interferometer. | ||
