ABSTRACT:
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.
