Acousto-optical coherence tomography (AOCT) is a variant of acousto-optic imaging (also called ultrasound modulated optical tomography) that makes possible to get resolution along the ultrasound propagation axis . We present here AOCT experimental results, and we study how the resolution depends on time step between phase jumps , or on the correlation length . By working at low resolution, we perform a quantitative comparison of the measurements with the theoretical point spread function. We also present images recorded with different resolution, and we qualitatively show how the image quality varies with , or .
