Correlation Function Profile Analysis in Laser Light Scattering II. A Hybrid Photon Correlation Spectrometer
We present a 256-channel single-clipped, dual delay time correlator. The PDP 11/35 computer acts as an accumulator for the time correlation function, essentially without limit. Software control allows synchronous start and stop of the correlator front-end, selective delay-time accumulation, and automatic intensity and time correlation measurements as a function of scattering angle. A specific comparison of percent relative error of linewidths and amplitudes of a double exponential time correlation function using single and dual delay times are presented.
