SCANNER/DECODER MULTIPLEX SYSTEM

摘要

A time division multiplex optical scanning system is disclosed capable of sampling a number of optical scanners, each of which scans at a predetermined scan rate including a plurality of scanners each including a rotatable support means having a plurality of reflective members disposed about its periphery for scanning an object as the support means rotates; and means for rotating the rotatable support means in a predetermined phase relationship with the rotatable support means of each of the other ones of the scanners for enabling the scanners to scan one at a time in sequence; means responsive to radiation reflected from the members for producing an electrical signal that is a function of the reflected radiation; means for generating time frames at a rate equal to the scan rate, each frame having a predetermined number of time slots equal to the number of scanners capable of being sampled; and means responsive to the means for generating for sampling the electrical signal from each of the scanners during successive ones of the time slots during each frame.
