Abstract
We describe a low-cost modification based on the research of Arecchi et al. [Opt. Commun. 3, 284–288 (1971)] on a standard photon correlation spectroscopy setup for measuring small (≃1%) and fast (resolution, ≃10 ns) light fluctuations. Details of the electronics and optics permit the apparatus to be easily reproduced. Careful tests show that spurious correlations of ≤1% can be achieved with standard detectors only when taking precautions with the electronics. Moreover, measurements on latex spheres, ellipsoids, and protein solutions show that fast and very small light fluctuations (≃1-5%) can be studied versus scattering vector and light polarization.
