Not Accessible

Your library or personal account may give you access

Abstract

We present an FFT-based software autocorrelator which was controlled by LabVIEW for DCS. Without much compromise in speed, the minimum decay time is in µ-second scale. Not only is it cost-effective, but also is flexible for raw signal processing.
