Uncertainty of Spot Moment Parameters Measured with Array Detectors
To calculate and to evaluate uncertainty of spot moment parameters measured with array detectors are the main goals. First, according to the integral expression of spot moment parameters, the corresponding discrete expressions of them are derived approximating zero order, and uncertainties of position and light power of every detector unit are analyzed preliminarily. General expressions of uncertainty of spot moment parameters are derived according to the transfer law of uncertainty. And then several simple forms of them are derived on corresponding conditions. So the methods of calculating spot moment parameters and evaluating the uncertainty of them are completely developed. Analysis on uncertainty of spot moment parameters measured with laser intensity distribution analyser (LIDA) and CCD are provided at last.
