The
Creation of a 3D Display Hologram
STEP 1 -
Mastering
|
The subject or model to be holographed is placed in front of the HS main optical unit (see left). The unit control is set to "mastering mode" and the direction and intensity of the illumination light is dialed up. The visual effect of the selected lighting may be confirmed by activating a series of test "flashes" known as the laser pilot mode. |

When
a satisfactory illumination has been obtained and the holographer
is happy with his scene, an unexposed holographic photoplate or
film is loaded into the main plate-holder and, at a chosen moment,
a full-energy laser pulse is activated. The laser light that is reflected from the subject or model contains not only the standard information that a photograph contains but also information about the 3D shape of the subject. This information is recorded onto the holographic photoplate. The holographic photoplate is now chemically processed and dried, after which it may be used in the "transferring" process described on the next page, in order to generate final holograms that are viewable in white-light. Chemical development of the master hologram is a process very similar to conventional B&W photography. For the development of holographic photofilm, photopaper developing machines may be used. |

Different Solutions to Mastering... Geola produces two types of holography systems:
The main difference between these systems is that the HS is designed to be installed in a fixed location and enables one to produce both the holographic master and the final hologram. The HS-M, however, is a portable system that can be taken to any location in order to shoot a master (without a darkroom). The HS-M cannot itself produce a final hologram that is viewable in white-light. For this, the holographic transfer of the master produced by a HS-M must be done in a HS Holographic Studio. |
