Abstract

A self-scanning linear array (10) is moved (12) in the image plane of a lens to thereby scan the image of an object which has been focused in the image plane. A random access controller controls random access to the information within the scanned image. Commands (14) including mechanical positional parameters (16) and electronic scan parameters (18) are decoded by the master microprocessor (20). The electronic scan parameters in the command provide information such as a user selected transverse axis frame size scan output of the array. An address generator (22) generates addresses in response to output pulses from the array. A windowing sequencer (24) in conjunction with the address generator (22) selectively gates particular ones of the pulses in the train of output pulses from the array in accordance with the electronic scan parameters in the command. The positional parameters (16) in the command provide information as to a user selected mechanical position of the array such as longitudinal axis frame size and longitudinal position axis seek. A position indicator (26) generates position representations in response to the physical position of the array (12), and a servo loop inclu…
