Holographic ballistic gravimeter with the fixation of the angular position of a test mass

We have reported on the results of an experimental simulation of a holographic absolute ballistic gravimeter with the minimal (down to 0.5 mm) length of the trajectory of a falling test mass and rigid stabilization of its angular position. Gravimeters of this type ensure the mobile measurement of the free fall acceleration and are intended for the application in a new field of research, i.e., HF gravimetry.
