Optical spectrum analyzer |
摘要 |
An optical spectrum analyzer has a deflection section for changing an incidence angle of measured light on a diffraction grating, a plurality of light detection sections for detecting the dispersed measured light and outputting an electric signal responsive to the light strength, and a signal processing section for finding an optical spectrum of the measured light based on the electric signal from the light detection sections. The light detection sections are arranged along the wavelength dispersion direction of the diffraction grating and output electric signals independently of each other.
