We report a holographic imaging technique for monitoring electrical breakdown. Proof-of-concept experiment of imaging breakdown in air is demonstrated. It is shown that the holographically captured amplitude and phase information can be used to visualize the breakdown process and calculate the electron density of the generated plasma. A temporal resolution of about 5 ns is accomplished, which is limited by the laser pulse duration time.
