Beschreibung
Zusammenfassung:	A wavelength meter can be combined with optical elements to measure the wavelength for changing communication channel by adjusting the wavelength. The wavelength meter has two wavelength dependent interferometers respectively with lower sensitive within large wavelength ranges and higher sensitive within small wavelength ranges. Each interferometer provides an output signal having an intensity varies with wavelength. By the interferometer with lower sensitive within large wavelength ranges, it determines the substantially wavelength range. And then uses the interferometer with higher sensitive within small wavelength ranges to measure the accurate wavelength of the input light beams.
