Abstract

Current CRT technology suffers from a reduced bright image response, and a reduced image resolution due to the distribution of beam current densities following a Gaussian rather than a uniform distribution. A uniform distribution of beam current necessary achieved by proper manipulation of CRT's electro-static focusing system. Functional connection has been found between three electrodes of CRT's electro-static focusing systems, which provide Laminar electron flow in system. This technology provides unique characteristics that is providing uniformly distributed output current density. Theoretical analysis is given for some current Electro-optical systems through the calculation of trajectories of electrons in the system without taking into account the different starting velocities. This analysis proves the importance of producing the Electro-optical systems with uniform distribution of current density. As the result it has been achieved ideal explicitness of the image and picture compression from 1 (transfer 1:1, for night vision devices) to 50 times (transfer 1:0.02, for electron-optics transmission) and more accompanied by uniform distribution of current density. Usage of this technology allows 10 time's reduction of time resolution and 2500 times increasing of light intensity for a compression of 50x. There is no need in corrective electrode in order to achieve high power brightness. With this technology no gain correction is required.
