| Abstract: | In this paper,the constitution and operation principle of an automatic system for laser power meter cali-bration are presented.Two kinds of calibration methods,direct measure and realtime monitoring,and their flow dia-grams are introduced.The measurement uncertainty is also evaluated.Our experiment indicates that the measurement uncertainty caused by data collecting and processing are respectively0.2%and0.01%,and that the expanded uncer-tainty is2.0%. |
