Abstract

A new method of ultrasound-modulated optical tomography is reported, in which the buried object in optical turbid media is imaged directly with frequency-domain signals by real-time FFT. Tunable near-infrared laser is modulated by focused ultrasound. 2D tomographic images are obtained through scanning and detecting the ultrasound-modulated optical signal. Multi-wavelengths laser and diverse frequency ultrasounds are used to study image quality.
