发明名称 |
Digital frequency synthesizer for use with precision AO scanning and positioning |
摘要 |
The invention comprises a digital frequency generator particularly adapted for use with acousto-optical scanning devices, and particularly for such devices as for producing a scan or a raster scan or the like. The invention electronic circuitry includes a precision timing generator which is made up of a tapped delay line which feeds a multiplexor to produce an output pulse of any desired configuration. The output pulses are produced in a stream, but each pulse is produced individually.
