Notes from the Open Discussion on 'Detection, Imaging and Characterisation of Objects through Barriers: Can we do this?'

摘要

For reasons of technical challenges and cost, the THz waveband is the last region of the electromagnetic spectrum to be evaluated and exploited. The aim of this session was to debate the claims put forward by people researching this frequency about its detection and resolution capabilities, particularly against obscured or hidden materials and objects. Here is an example of the type of claim encountered: ...The researchers demonstrated that they could detect the signal from 67 feet away, the length of their laboratory space, but theoretically they could identify materials hundreds of feet or even miles away.
