Abstract
Apparatus for high speed analog data recording utilizing a new tube design (referred to herein as a photonic cathode ray tube) is presented. The photonic cathode ray tube includes a flat photocathode, a small aperture electron lensing system, a set of deflection plates and a phosphor screen.
Claims31
A photonic cathode ray tube comprising:
- vacuum tube means having opposed first and second ends;
- photocathode means in said tube means at said first end of said tube means;
- phosphor screen means in said tube means at said second end of said tube means;
- electron focussing lens means disposed in said tube means in close proximity to said photocathode, said lens means including a small aperture therethrough, said aperture having a diameter of about 1 mm;
- and
- deflection plate means in said tube means, said deflection plate means being between said lens means and said second end of said tube means.
