Portable holographic camera for manufacturing high-quality volume reflection holograms

摘要

The portable holographic camera for manufacturing high-quality volume reflection holograms reconstructed optically by white light has been designed. The holographic setup comprises a low-power He-Ne laser. The design of the holographic camera is the development of the holographic sandbox technique. High-silica sand is used for mechanical and temperature stabilization. A rigid mounting of an object and photographic plate is not provided for the construction of the holographic camera. This makes possible the high rate of photographic plates changing. The processing arrangement is designed for manufacturing several tens of high-quality reflection holograms in one operating cycle. The portable holographic camera has been used very successfully for making holograms of museum objects.
