Hard to believe. What's the secret to see them ?
- sqquuiiiddd 9y agoA simple coil of wire could act as a receiver. And attached to a light emitter, the strength of the signal would translate to a brighter light. Just a guess though.
- piptastic 9y agoThey have a video you can watch
- saeranv 9y agoThe video doesn't really explain what they're doing though. Can anyone explain how they're visualizing the EM fields here?
- mmcconnell1618 9y agoIt looks like they have a metering device that glows different colors based on the strength of the field detected. They then appear to be systematically moving the meter across a grid with time lapse photography. The lights photographed from different positions are blended together to create a voxel-like view of the field.
- saeranv 9y agoThanks for explaining that makes sense. What kind of metering device will glow based on these kinds of EM fields?
