摘要： A characteristic of an optical property of a device under test-DUT-(50) is determined by providing to the DUT (50) a first laser signal at a first center wavelength, modulated by a first modulation frequency, and a second laser signal at a second center wavelength, modulated by a second modulation frequency. Response signals from the DUT (50) on the applied first and second laser signals are received. The characteristic of the optical property of the DUT (50) is then determined based on an analysis of the received response signals for different measurement setups of parameter settings for the first center wavelength, the first modulation frequency, the second center wavelength, and the second modulation frequency, in conjunction with the parameter settings for each measurement setup.
