Shot-noise detection of ultrasound-tagged photons in ultrasound-modulated optical imaging

Not Accessible

Your library or personal account may give you access

Abstract

We propose a new detection method for ultrasound-modulated optical tomography that allows us to perform parallel speckle detection with optimum shot-noise sensitivity, using a CCD camera. Moreover, we show that making use of a spatial filter system allows us to fully filter out speckle decorrelation noise. This method is confirmed by a test experiment.
