LIGHT WAVELENGTH MEASUREMENT METHOD AND LIGHT WAVELENGTH MEASUREMENT APPARATUS |
摘要 |
A light wavelength measurement method of measuring a wavelength of target light includes: receiving target light on a second dispersion device that disperses the target light into a plurality of second beams which reach a plurality of positions corresponding to the wavelength of the target light (S106, S202); and measuring the wavelength of the target light, by using the plurality of the second beams as a vernier scale for measuring the wavelength of the target light within a wavelength range specified by a main scale (S108, S204). |
