Visualizing RFID

jamie found a video on Warren Ellis's blog introducing a new way to visualize RFID fields. The film is by Timo Arnall and Jack Schulze. The subject is introduced in words on the BERG site (a design consultancy); the tech behind it is explored at Touch, a project that experiments with near-field communications. "This image is a photographic mapping of the readable volume of a radio field from an RFID reader. The black component in the image is an RFID reader... The camera has been fixed in its position and the reader photographed. Using a tag connected to an LED we paint in the edges of the readable volume with a long exposure and animate them to show the form."

Re:The field patterns of loop antennas

[buchner.johannes]

Electromagnetism is not new, no. Your link shows a field produced by a antenna, which is only a theoretical concept (abstracting away the measuring sensor).
What the pictures in TFA show is the dependency of the field vs. the direction of the measuring device, i.e. a slice of a vector field B(x).

But I do believe that the makers were not interested in the technical aspect, but a design/architectural/artistic aspect.
