  • Title: Autocorrelation of scattered laser light for ultrasound-modulated optical tomography in dense turbid media.
    Author: Li H, Wang LV.
    Journal: Appl Opt; 2002 Aug 01; 41(22):4739-42. PubMed ID: 12153111.
    Abstract:
    Based on measurement of the intensity autocorrelation function, a new method to determine the modulation depth of scattered laser light modulated by an ultrasonic wave in turbid media was applied to ultrasound-modulated optical tomography. Good signal-to-noise ratios and high sensitivities were demonstrated. Images of double optically absorbing objects buried in a highly optically scattering gel sample were obtained. The contrast was more than 10%, and the spatial resolution was approximately 2 mm.
