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

摘要

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