title: Full-photon-counting Rayleigh spectrometer: a correlation and/or fast Fourier transform instrument.
abstract: A fast, flexible, and relatively inexpensive minicomputer based Rayleigh spectrometer has been constructed. This spectrometer can utilize photon pulses in a most efficient way by performing autocorrelation and/or FFT with any desired number of channels. Its capability has been demonstrated by measuring large latex particles, small sodium dodecyl sulfate micelles, and a polydisperse latex-gamma-globulin system. Detailed timing diagrams and circuit schematics are also included.
