Abstract
An electronic image camera system including an image receiving and storing device therefor comprises a stimulable phosphor, and a multiple electrode configuration associated therewith for storing a plurality of images therein in accordance with the selective energization of selected ones of the plurality of electrodes, the images being selectively retrievable in an ordered sequence by addressing the stimulable phosphor with a stimulating light in regions immediately adjacent selected ones of the electrodes.
Claims14
An electronic image camera apparatus including an objective lens for focusing scene light received from each of a plurality of succeeding subjects to be recorded and means for defining an aperture for admitting the focused scene light to the camera apparatus and for determining an exposure interval for each one of the plurality of succeeding subjects, said camera comprising:
- means responsive to the scene light received by way of the objective lens and aperture defining means for converting the photons of the scene light into electrons representative of an image of the subject to be recorded;
- means for receiving the electrons from said converting means and intensifying the electron representation of the image of the subject to be recorded, said intensified electrons exiting from an output side of said intensifier means;
- a plurality of electrodes spaced apart with respect to each other and disposed in an interleaved pattern on a plane spaced apart from said output side of said intensifying means;
- means for energizing a selected one of said interleaved electrodes for each exposure interval so as to define an electron accelerating gap between the output side of said intensifying means and that one of said electrodes selected for energization whereby electrons representative of each subject are accelerated from the output side of said intensifying means toward that one of the interleaved electrodes selected for energization;
- a stimulable phosphor disposed adjacent the plane of said interleaved electrodes for storing the electrons accelerated by said interleaved electrodes in the pattern of each one of said interleaved electrodes so energized;
- means for stimulating the stimulable phosphor in the pattern of selected ones of said interleaved electrodes so as to cause said stimulable phosphor to emit subject defining light in the pattern of said selected electrodes;
- and
- means for sensing the subject defining light emitted by said stimulable phosphor and converting said sensed subject defining light to an electronic information signal representative of the subject, said electronic information signal being readily recordable and convertible to a visual display of the subject.
An image receiving and storing apparatus for use in an electronic imaging camera, said apparatus comprising:
- means responsive to scene light received by the camera for converting the photons of the scene light into electrons representative of an image of the scene to be recorded by the camera;
- means for receiving the electrons from said converting means and intensifying the electron representation of the image of the scene to be recorded by the camera, said intensified electrons exiting from an output side of said intensifier means;
- a plurality of electrodes spaced apart with respect to each other and disposed in an interleaved pattern on a plane spaced apart from said output side of said intensifying means so as to define an electron accelerating gap between the output side of said intensifying means and each one of said interleaved electrodes upon its energization;
- and
- a stimulable phosphor disposed adjacent the plane of said interleaved electrodes for storing the electrons accelerated by said interleaved electrodes in the pattern of each one of said interleaved electrodes so energized.
