Abstract
Ultrasound modulated optical tomography (USMOT) can image the optical properties of a scattering
medium at a spatial resolution approaching that of ultrasound (US). A lock-in parallel speckle detection
technique is proposed to detect pulsed US modulated light using a multipixel detector. The frequency
components of the pass band match those of the US pulse train and provide efficient detection. The modulation
depth is extracted by taking the difference between a pair of speckle patterns modulated by a pair
of phase-inversed US bursts. Modification to pulse inversion mode enables the second harmonic US
modulation due to nonlinear US propagation to be detected. © 2013 Optical Society of America
