Alarming Spy Device Can Read Text in an Open Book From Nearly a Mile Away

Alarming Spy Device Can Read Text in an Open Book From Nearly a Mile Away Enhance! Dark Lord's Spy Scientists say they've developed a ludicrously keen-eyed laser device that can read the text in a book from a whopping 0.85 miles away. As detailed in a new paper published in the journal Physical Review Letters, the team used interferometry, a commonly used technique in the world of astronomy that uses superimposed waves of light to create interference patterns, to develop the spy system. However, instead of combining waves of radiation, light, or sound, the team used the information collected by multiple light detectors to measure variations in intensity, a technique known as intensity interferometry. They then used this data to compile an image of a distant object. Put simply, researchers applied a technology that space observatories use to a ground-based laser system to zoom across vast distances — with promising and somewhat creepy results.
