The method of ``live‐fringe'' holographic interferometry has been adapted for use on transmission objects with two ruby lasers replacing the customary cw laser. The hologram is produced with a giant pulse laser and reconstructed with another laser having a pulse width of 50 &mgr;sec. Consecutive, real time interferograms can be obtained during this period with image converter cameras pulsed on for as little as 0.1‐&mgr;sec intervals.
