DEVELOPMENT
OF THE NEW GDV DEVICES
Conclusion
Data
received suggest that using different covers does not create
any advantages compared with clear lens of the GDV Camera
(standard screen), whereas using vacuum screen may give some
advantages due to the higher parameters of the GDV image and
decrease in applied voltage. In principle, this creates possibility
for development of the portable GDV Camera, operating from
the battery. This line needs more experimental research.
