A holographic imaging apparatus having a pulsed laser light source for generating an object beam and a reference beam whereby an object, obscured by a diffusing medium, is illuminated by the object beam. A real time interferogram recording medium is exposed to the coincidence of light reflected from the object and the reference beam to record an interferogram. A holographic image is then reconstructed from the interferogram and may be viewed and recorded. The pulsed laser light source generates a beam which is divided by a conventional beam splitter device into an object beam and a reference beam. The object beam is then diverged by a lens which forms a diverging object beam to illuminate the object. The reference beam is diverged through another lens to form a diverging reference beam which is directed so that it illuminates a photoreactive crystal. The coincidence of the reflected light and diverging reference beam generates a pattern of interference fringes known as an interferogram which is recorded by the crystal. The apparatus can use time-gating in the holographic medium to use ballistic and snake-like light, which arrives before scattered light, to construct a holographic image. The apparatus can also obtain depth information for 3-D images by using the time-gating technique to obtain the image bearing light from a 3-D object. The apparatus also may record light-in-flight images of the object, to record different depths of the object separately, by using an optical delay assembly.
