ABSTRACT

Acousto-optic imaging promises to provide in vivo images of optical contrast but with the superior spatial resolution of ultrasound imaging. Here we present novel quadrature detection of ultrasound-modulated photons with a gainmodulated, image-intensified, CCD camera. The additional detection of ultrasound-modulated fluorescence photons demonstrates potential for in vivo acousto-optic molecular imaging.
