One-step two-wavelength holography is obtained with two interferometric beams with different wavelengths by means of a polarizing modulation produced by a liquid-crystal light valve. This holographic method eliminates the need for preliminary static recording of the hologram and permits one-step two-wavelength holographic testing to produce results easily in real time.
