How I measure coherence with the Sputnik GDV camera
The technical detail of how I read a space's electromagnetic "pulse" through environmental bioelectrography.
Knowing the real electromagnetic stability of a space takes more than measuring how much field is present at a given moment: you also need to know whether that field behaves coherently or chaotically over time. For that I use the Sputnik GDV camera, a sensor that, rather than giving a single-point reading like a conventional meter, captures how a small electrical stimulus reacts to the room's electromagnetic environment.
I place the sensor at one or several representative points in the space (the centre, the corners, areas where people spend the most time), and at each point I take dozens of consecutive readings, from which I extract three complementary indicators: the coefficient of variation of the energy, which shows how consistent or scattered the readings are; the entropy, which indicates whether the field is organised or tends toward chaos; and the level of ambient activity, which reflects how much energetic "movement" there is in the environment.
None of the three tells the whole story on its own, so I cross-reference them to distinguish a real change in coherence from a simple measurement artefact. Comparing these results across the different points gives me a reliable picture of the electromagnetic stability of the whole room: not just intensity, but quality and real behaviour — which is ultimately what determines whether a space is healthy to spend time in.
A note on precision: I use "coherence" in two distinct senses. In field physics, it refers to the regularity and polarisation of the electromagnetic wave — a real property that distinguishes artificial fields from natural ones.1 In environmental electrophotonics (Sputnik), coherence is calculated from the entropy and standard deviation of the recorded light pattern, following the GDV methodology developed by Korotkov and his team.2 These are two complementary measurements within my method, not the same physical quantity.
