In the world there are a lot of cultural assets which are suffering from the process of abrasion and discoloration due to environment change and industrialization. Especially the cultural assets that are situated or displayed in metropolitan areas have been seriously damaged and deteriorated at this very moment. Moreover, this process is irreversible. That means even if we restore them, it is hard to take back it originality. So we need urgent measures to protect these assets and pass down our precious legacies to next generation. Digital conservation methodology would give some clue to solve this problem.
Holography is an optical technique that enables virtual three-dimensional replica of certain objects to be made. The value of this technique is very high as the purpose of cultural asset conservation, because hologram creates almost similar exhibition effect of cultural properties with high accuracy and resolution. Here is the video clip to show how sophisticate it is.
Hologram has gain acceptance in museum exhibition. The biggest problem of cultural assets’ exhibition was meeting the basic requirements – such as displaying location and conservation condition. As tangible cultural assets are rare and nonrenewable, they should be kept in a well-controlled environment. On top of that, vibration problems and safety issues are taken into consideration, in the case of moving to a new place to exhibit. However, these problems can be easily solved by using holography technique.
Hologram, which is sort of special coating glass plates, is easy to install and doesn’t require large space. In addition, once master hologram was produced, it reproduces the images continuously. Therefore, it offers us two important freedoms; freedom of physical space and freedom of time. These freedoms give benefits to not only the public but also the researchers. Holography can be applied around the world for cultural comparative display and research, maintaining the originality of the local museum, and restoring vulnerable heritages.
Digital technique is changing displaying paradigm as well as platform. For a long time, museum patrons have appreciated cultural heritages passively. However, digital museum enables us to offer “vivid-historical travel contents” experience, by recreating historical place and incident with story-telling. Spectators can be deeply involved in each well-organized imaginary episode and time-travel back in the past. Digital museum realizes people’s long-cherished dream.
