| Abstract: | The principle of measuring spectrum is described,based on fast Fourier transform for the interference pattern from the diffraction of light through the side of a fiber grating.The range of measurable optical wavelengths and resolvable wavelength interval are discussed.The some problems,which must be considered in designing fiber grating and selecting CCD detectors,are given.This spectrum analyzing method has the advantages of high resolution of spectrum,simple structure and low price etc. |
