摘要: We have developed a new method for characterizing the irradiance responsivity of filter radiometers. The is based on spatially uniform, known irradiance, generated by combining several identical laser beams. measurement setup and experimental demonstration at one wavelength are presented. diffraction correction related to studied experimentally. uncertainty analysis indicates relative standard 1 × 10-3. results with compared characterization measurements our present spectral-irradiance scale. deviation 10-3, which well within combined comparison.
