The GREEF portable holographic camera has been created for recording transmissive-type 30×40-cm holograms. A solid-state pulsed neodymium glass laser that generates radiation in the visible region (λ=526 nm) with energy 1 J and pulse width 30 ns is used in the camera as a coherent light source. The fact that the optical elements of the pulsed laser and the setup for shaping the object and reference beams are combined in one housing and the use of removable diffusers and original optical systems allowed the size and weight of the camera to be reduced. The camera is intended for recording holographic portraits of people and for obtaining holographic replicas of representatives of flora and fauna, museum exhibits, and other objects, including those recorded under conditions of off-site imaging.
