Abstract

A novel frequency-swept (chirped) ultrasound modulated optical tomography technique was developed to image scattering media. Laser light was modulated by a frequency-swept ultrasonic wave to add spatial information to the modulated optical signal. The modulated optical signal was received by a photomultiplier tube and was heterodyned with a reference modulation signal. Frequency analysis was employed to obtain spatial resolution along the ultrasonic axis. A spectrum can be converted to a ID image. Multiple spectra were obtained and were used to form a 2D image of the scattering medium.
