In the history of Science, developing of a new instrument has always resulted in new understanding of Reality. Microscope, telescope, X-rays, camera, laser, computer - without these instruments the modern science is powerless. Recently a new instrument came to being - a solid state computerised Gas Discharge Visualisation (GDV) camera for bio-electrography.

GDV of a human fingertip

Internationally distinguished biophysicist, Prof Konstantin Korotkov from St. Petersburg Tech University in Russia studied the information aspect of stimulated electro-photonic emissions around the human body and other objects for more than two decades. He found, that in order to be able to extract reliable and repeatable information from the recorded electro-photonic glow it was necessary to optimise the apparatus.

In particular it was necessary to minimise the influence of the ambient temperature and humidity, use a semiconductor camera rather than a photographic process for recording images and optimise parameters of the process of stimulation of electro-photonic emissions. In 1996 Prof Korotkov developed a range of instruments for stimulation, recording and processing of electro-photonic images and called his technique Gas Discharge Visualisation (GDV).
