Application 08/026,797
microchannel plate (MCP) improves the spatial resolution of
proximity focused image intensifiers.
One of the prior approaches for improving the resolution of
proximity focused image intensifiers (Specification, p.2):
[I]nvolves the use of microchannel plates
wherein the ground plane thereof is located
in closely spaced relation to the phosphor
screen having a positive potential applied
thereto. If a high voltage is applied to
improve to [sic] resolution of the image
intensifying device, there is a breakdown,
thereby requiring such devices to operate a
[sic] lower than desired voltages.
According to appellant, the spatial resolution of these devices
can be improved without creating a breakdown (Specification, p.8;
see also Figure 3):
[B]y coating the ground plane of an MCP so as
not to obstruct the holes in MCP, the
phosphor screen can be located closer to the
MCP and the voltage can be significantly
increased, thus greatly improving spatial
resolution [emphasis added].
