RELATION BETWEEN THE EODM PRECISION AND THE RETURN LIGHT SIGNAL

Starting from the range equations of EODM , this paper discusses the following problems: the ef-fecf of the atmospheric decrement upon the EODM return light intensity; the statistics of linear analysis for the relation between EODM precision and the return light signals ; presentation of new precision ex-pression for the experimental instruments by experimental data statistics. The paper points out that the return light signal is an important information reflecting the atmospheric status for the measuring lines; the EODM precision is closely correlated with the atmospheric status of the measuring lines ; the introduc-tion of the measured return light signal to the precision expression can objectively reflect the EODM preci-sion and make the adjustment result possessing the superiority of good uniformity etc.
