专利汇可以提供Optical spectrum analyzer专利检索,专利查询,专利分析的服务。并且PURPOSE:To display a spectrum with resolution at almost equal intervals over the entire wavelength range by making the power of power converting circuit different and displaying the spectrum of nearly equal wavelength resolution. CONSTITUTION:A desired measurement range is set with a lower-limit wavelength and an upper-limit wavelength within a wavelength range prescribed by a setting means 21. Those lower-limit and upper-limit wavelengths are converted by a wavelength-frequency converting means 17A to corresponding frequencies. Then, a deciding means 17B decides whether or not a prescribed switching frequency is present in the set range. When the frequency is present, a band calculating means 17C calculates the 1st band width between the frequency corresponding to the short-wavelength side lower-limit wavelength and the switching frequency and the 2nd band width between the switching frequency and the frequency corresponding to the longer-wavelength side upper-limit wavelength. A resolution correcting means 17D uses the 1st and the 2nd band widths to process respective thinning-out rates found on the short-wavelength and long-wavelength sides and data fetched at a center frequency by Fourier transform 18, and the data are displayed 9.,下面是Optical spectrum analyzer专利的具体信息内容。
