Detection limit in localizing objects hidden in a turbid medium using an optically scanned phased array

Abstract

In this paper the sensitivity of a phased array and a continuous wave measurement setup are compared. Both techniques are used to image inhomogeneities hidden inside a tissuelike turbid medium. We have found that despite the higher technical complexity of the phased array measurement, its sensitivity in detecting inhomogeneities is virtually the same as the sensitivity of the continuous wave measurement.
