We demonstrate a prototype light scattering instrument combining a frequency\ndomain approach to the intermediate scattering function from Super-Heterodyning\nDoppler Velocimetry with the versatility of a standard homodyne Dynamic Light\nScattering goniometer setup for investigations over a large range of scattering\nvectors. Comparing to reference experiments in correlation-time domain, we show\nthat the novel approach can determine diffusion constants and hence\nhydrodynamic radii with high precision and accuracy. Possible future\napplications are discussed shortly.\n
