OSA Member Talks Holograms on NPR

12. November 2008

Posted by Christina Folz, OPN Managing Editor 

The Nov. 11 Kojo Nnamdi show on NPR featured a fascinating interview with OSA member Tung H. Jeong, professor emeritus at Lake Forest College. Jeong discussed the technology of holograms as part of the show's "Tech Tuesday" segment. Jeong was asked about CNN's use of a so-called "holographic" technology when it beamed 3D images of its guests into the network's studio on election night. Jeong pointed out that those images were not actual holograms--and explained why. In fact, he said, "there is no relationship between the two except showing images." Jeong was later joined by physicist Hans Jurgen Kreuzer of Dalhousie University in Nova Scotia. The two described how the field of holography is advancing to include new applications in data storage, cellular manipulation, and holographic 3D TV. Regarding the latter: Because everyone would have to wear their own special glasses to see the holographic images, a key advantage is that "you don't have to fight for the remote," Jeong said.

I´d like to make a remark of "everyone would have to wear their own special glasses to see the holographic images"
in the last sentence of your short article. This most likely refers to a stereoscopic device needing polarizing
or other glasses assigning the left and right images to the appropriate eyes.
Holography, instead, doesn´t need such a means. It produces the light distribution exacly as it emerges from
the (virual) object itself. In principle, you won´t be able to distinguish between viewing an object or its
holographic reconstruction.
BTW, we are developing holograms for TV.
