在高能激光能量测量装置标定方法中，现场标定的方法可以有效地消除各种外在因素对测量结果造成的影响。介绍了3种现场标定方法，分析了这3种方法的原理以及数据处理过程。由于标定中多个参量未知，因此采用了最小二乘法拟合。对于分光镜反射率和透射率比值不确定造成的影响，采用了现场标定分光比的方法予以消除。通过对实验数据分析和比较可以看出直接传递法最简单，可有效消除环境因素、激光光斑特性等造成的影响；间接传递法可以同时消除包括分光比改变在内的几乎所有外在因素造成的影响，但是由于标定过程较复杂，测量不确定最大；交叉传递法标定过程比间接传递法简单，同时也可以消除分光镜分光比改变产生的影响，且数据处理过程是这3种方法中最简单的。

In the calibration methods for high energy laser(HEL) energy measuring equipment, the online calibration method can eliminate vourous effect imposed on measurement results by extrinsic elements. Three online calibration methods were introduced to analyse the theories and data treatment processes. Since several parameters are unknown, least square fitting method was used. The ratio of reflectivity to the spectroscope transmittance was calibrated online to eliminate its uncertainty imposed on the measurement results. By analyzing and comparing data of the three methods conclusions show that direct transfer method is the simplest which can eliminate effect caused by environment elements, laser beam spot characteristic, and so on. Indirect transfer method can eliminate the effect caused by almost all extrinsic elements including change of the ratio of reflectivity to transmittance, but its calibration processes are complex, its uncertainty in measurements is the biggest. Calibration processes of intersectional transfer method are simpler than indirect transfer method’s. It can also eliminate effect caused by changes of the ratio of reflectivity to the spectroscope transmittance, and its data treatment processes are the simplest.
