ABSTRACT We demonstrate a new design for a light-scattering microscope that is convenient to use and that allows simultaneous imaging and light scattering. The design is motivated by the growing use of thermal fluctuations to probe the viscoelastic properties of complex inhomogeneous environments. We demonstrate measurements of an optically nonergodic sample, one of the most challenging light-scattering applications.

    ABSTRACT: Rayleigh light scattering has not yet been used for quantitative investigations of heterogeneous systems. Preconditions such an experiment are a well defined scattering geometry and independent information about the local state of the sample. We have designed a new instrument that meets these criteria: a light-scattering microscope with simultaneous imaging. We demonstrate the ability to characterize local differences within one tissue type as well as global differences between tissue types. Real space images of the sample are taken by normal video microscopy techniques. The light scattering pattern in analyzed by the evaluation of wave-vector dependence and scattering direction of the scattered intensity. Statistical analysis of scattering patterns show what is important for the characterization and classification of tissues and heterogeneous structures. Real space images provide context for scattering analysis. The light scattering microscope is a powerful tool for characterization of local structural order in inhomogeneous structures like tissues.

    ABSTRACT: We describe a new design for a microscope-based static light-scattering instrument that provides simultaneous high-resolution images and static light-scattering data. By correlating real space images with scattering patterns, we can interpret measurements from heterogeneous samples, which we illustrate by using biological tissue.

    ABSTRACT: A novel microscopic photon correlation spectrometer has been designed and developed in order to employ photon correlation spectroscopy to investigate dynamic properties within a microscopic volume. It shows a spatial resolution scale of about 0.5 micrometres and a relaxation timescale of milliseconds. The variance of the scattering vector is less than 5% even at a smaller scattering angle. Furthermore, a standard performance test using 94±13 nm polystyrene latex beads has been performed on the apparatus. The autocorrelation function value at the first channel is higher than 0.8, that indicates a higher signal-to-noise ratio and a good coherent detection. CONTIN analysis gives the latex beads size as 94±2 nm. Different angle scattering results give the translation diffusion coefficient (4.57±0.08)×10-8 cm2 s-1 at 293.15 K, that agrees with the theory very well. Besides, scattering spectroscopy using different pinhole sizes determines the optimized configuration for the spectrometer with higher accuracy. All these document that the designed system works much more accurately than previous systems and may probe dynamic information from different local sites of a single living cell non-invasively.
