Correlation investigation of the brightness of GDE-grams using the methods of computer graphics and direct measurements

There are two methods of measuring the glow a liquid under conditions gas-discharge imaging. This is investigation brightness GD-grams - digital image streamers created these conditions, and direct measurement using luminometer, which carried out during formation streamer gas discharge. In first case, analyzed computer graphics certain software. second, results analyzed. We have example water visualization. It shown that with measurements values ​​are higher than when investigating same obtained in time period. Namely 1.5 cd/m2 1.7 cd/m2. The difference 13% significantly exceeds error meter (± 7%). According to our research, we suggest that, at very least, calibrating devices create GDV-grams, use photometric units. For example,
