Phys. Rev. Lett. 85, 1416–1419 (2000)Space Intensity Correlations in the Near Field of the Scattered Light: A Direct Measurement of the Density Correlation Function g(r)Received 23 December 1999; published in the issue dated 14 August 2000 We show that the two point intensity correlation in the near field of the scattered light is directly related to the two point density correlation g(r). Preliminary measurements on two sets of calibrated random pinholes of 140 and 300μm diameters, and on aqueous solutions of latex spheres of 5, 10, and 40μm are reported. A discussion on the desirability of the technique as a simple and powerful alternative to low angle scattering will be presented. © 2000 The American Physical Society URL:
