400～1700nm绝对光谱响应度校准和量值传递
Calibration and Value Transmission of Absolute Spectral Responsivity between 400 nm and 1700 nm
摘要
Abstract
The principle and methods of optical radiation measurement was illustrated.The absolute spectral responsivity of Si trap detectors and InGaAs trap detectors were calibrated with the absolute cryogenic radiometer at eleven wavelengths between 400 nm and 1700 nm,which are 476.1,488,514.7,521,568,632.8,647.1,785,852,980,1064 and 1550 nm,respectively,with measurement uncertainties better than 0.05％.The absolute spectral responsivity curves of Si trap detectors were calculated by quantum efficiency model.The absolute responsivity of three wavelengths was applied to get absolute spectral responsivity from the relative spectral responsivity of InGaAs detector.Results show that the two types of trap detectors can be used to calibrate and transfer optical radiation value in the visible and near infrared spectral range.关键词
