ABSTRACT:
An electronic read/write or microscope-camera system which can receive and store very low energy optical and equivalent electronic signals on a special optoelectronic tape or medium as varying charge density distributions over the imaged frame. Images are retrieved from the tape or medium by scanning the tape or medium with a focused electron beam which causes the tape or medium to emit secondary electrons as a charge density modulated return beam current. The electrons in the return beam are collected and amplified to develop an electrical signal representative of the image stored on the tape or medium. A method of applying images to and retrieving them from the tape or medium is also disclosed.
