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.

摘要： An object of the invention is to realize an optical spectrum analyzer capable of performing high-speed waveform sweep. The invention is to make improvements to an optical spectrum analyzer for measuring a spectrum of light to be measured by collimating light to be measured by collimator means, spectroscopically separating the collimated light incident from the collimator means according to an incident angle by a diffraction grating, and detecting the light spectroscopically separated by the diffraction grating by a photodetector via a slit. The device is characterized by including an acoustooptic deflector provided between the collimator means and the diffraction grating for deflecting the collimated light to be measured and changing the incident angle on the diffraction grating.
