Wavelength Swept Light Source
Optical Sensing for Industry
A wavelength swept light source emits laser light with a continuously sweeping wavelength. It is suitable for shape measurement and displacement measurement utilizing OFDR (Optical Frequency Domain Reflectometry), an optical sensing method using the coherence of laser light. The OFDR method is also widely known as the FMCW (Frequency Modulated Continuous Wave) method.
