Wavelength tunable light source system having the wavelength measurement functions for hyperspectral imaging system

摘要

Wavelength tunable light source system having the wavelength measurement functions for hyperspectral imaging system is disclosed. Method is to detect the reference filtered tunable optical beam using steps that refer filtering a portion of the wavelength tunable light beam, at least one photodetector while adjusting the center wavelength, the reference filter it includes the step of generating at least one detector signal, and determining a variable center wavelength based on the at least one detector signal varies with the center wavelength from the tunable optical beam that is.
