Theoretical study of Acousto-optical coherence tomography using random phase jumps on US and light

摘要

Acousto-Optical Coherence Tomography (AOCT) is variant of Acousto OpticImaging (called also ultrasonic modulation imaging) that makes possible to getz resolution with acoustic and optic Continuous Wave (CW) beams. We describehere theoretically the AOCT e ect, and we show that the Acousto Optic taggedphotons remains coherent if they are generated within a speci c z region of thesample. We quantify the z selectivity for both the tagged photon eld, and forthe M. Lesa re et al. photorefractive signal.
