Image source, for converting image data in the form of serial charges into a high-resolution imagewise light pattern, combines semiconductor charge-coupled devices for receiving the charges, associated small-scale field emission arrays for converting the charges to imagewise pattern of electron emissions, an electron multiplier for intensifying the electron emissions, and a luminescent phosphor layer susceptible to light output according to the impact of the intensified electron emission. The light output may be directed onto a photosensitive image recording medium to provide for image recording. Second and third embodiments of the contemplated image source provide light output that forms an image to be viewed directly.

High resolution field emission image source and image recording apparatus

Image source, for converting image data in the form of serial charges into a high-resolution imagewise light pattern, includes a CCD emitter having a semiconductor charge-coupled device (CCD) structure for receiving and transferring the charges, a charge amplification means including a charge-modulated control field effect transistor structure (C-FET), and plural small-scale field emission cells (FEC). The CCD emitter is operable to convert the charges to an imagewise pattern of electron emissions that are directed to a luminescent phosphor layer susceptible to light output according to the impact of the incident electrons. The light output may be directed onto a photosensitive image recording medium to provide means for image recording, or in alternative embodiments, the light output may be viewed directly.

A corona discharge device having a first corona wire and a second corona wire parallel to the first corona wire and in physical contact therewith, such that the forces created by the wires during energization prevent the vibration of the wires, thereby eliminating short circuiting and the need for costly wire-damping devices.
