There is increasing demand for high resolution image sensor for applications
in high definition television, high resolution x-ray imaging in the medical
field. In order to meet the requirements of these applications, a high resolution
Plumbicon camera tube was developed at Philips Components.
A camera tube for high definition imaging is required to have high
sensitivity, good spectral response, high signal to noise ratio, low lag and
retention. The tube is designed with electrostatic deflection to achieve uniform
and high resolution. An additional design feature is the low capacitance target
for highest signal to noise ratio. This is especially important in wide bandwidth
high line rate systems. This feature in combination with new Plumbicon layer
technology provides the benefit of low light level contrast detectability.
