OPTICAL HETERODYNE SPECTRUM ANALYZER

摘要

PROBLEM TO BE SOLVED: To perform determination of wavelength and power values of a spectrum and their calibration such as correction with a simple configuration.;SOLUTION: A wave length detection part 200 detects a predetermined wavelength interval and transmits transmission light corresponding to a spectrum wavelength interval by allowing an etalon 11 to receive swept light output from a variable-wavelength light source and transmit the light at the predetermined wavelength interval. A measuring part 100 calibrates a spectrum detected by the wavelength detection parton the basis of the wavelengths of light to be measured whose powers have been measured. Moreover, based on each peak power corresponding to the predetermined wavelength interval output from the wavelength detection part, a correction part 10 corrects the power of the spectrum measured by the measuring part.;COPYRIGHT: (C)2010,JPO&INPIT
