Imaging devices using self-scanned arrays operating in the electron bombarded mode
Abstract
A description is presented of photosensitive electro-optical imaging devices which employ self-scanned solid state arrays (SSA) as transducers. In the considered operational approach, the light beam which contains the spatial or temporal distribution to be detected is focussed on a photocathode. Photoelectrons ejected from the cathode are accelerated and impinge on the surface of the SSA. Hole-electron pairs are formed in relation to the density and the energy of the impinging electrons. Advantages of the described approach are related to a wider spectral operational range and improved image modulation transfer. Attention is given to remote process tube technology, the proximity focussed intensified CCD (ICCD), a magnetic focussed ICCD, and sweep tubes with silicon diode arrays.
