WebThe values measured by the optical interrogator (data acquisition system) are the peak wavelengths of the narrow spectrum reflected by the fiber Bragg grating sensor. When strain at the optical strain sensor causes the wavelength to change, the interrogator detects a change in the peak wavelength that is proportional to the strain. WebCustom Diffraction Gratings. In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams traveling in different directions. The directions of the beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element.
