In inertial confinement fusion experiments, the measurement of hydrodynamic instability growth factor is an important means of studying hydrodynamic instability. In this paper we use the calibration of the sample to gain the modulation transfer function of framing camera at a given space frequency. The calibration results are employed to measure the absolute hydrodynamic instability growth of sinusoidally perturbed sample, under the condition of the same configure, and the growth factors at different times are given. The results show that the method of measuring the absolute hydroponics instability growth is established successfully.
