Paper Abstract

An accelerometer shock calibration system using grating laser interference technique is described in this paper. The shock acceleration value is directly and absolutely acquired from the base quantity and unit. The principle of the differential gating laser interferometer shock calibration device are introduced. Experimental results are given. The uncertainty of measurement is evaluated. The calibration uncertainty is in the range of 100 m/s2 to 100,000m/s2 is less than 2 percent and in the range of 100,000m/s2 to 1,000,000m/s2 less than 3 percent.
