New solid-state image scanner capable of random positioning

Studies were carried out on a solid-state image scanner that is able to scan and be addressed randomly. It consisted of a linear integrated-circuit array of photodiodes and metal-oxide-semiconductor transistors (MOST). It was found that the maximum scanning rate is about 1.5/spl times/10/SUP 5/ dot/s and that the value is mainly restricted by the charge-storage effect in the photodiode and stray capacitance between the gate and the source electrode of the MOST.
