We combined this technique with heterodyne off-axis digital holography. Two-dimensional images of absorbing objects embedded in scattering phantoms are obtained with a good signal-to-noise ratio. We study the impact of the phase modulation characteristics on the amplitude of the acousto-optic signal and on the contrast and apparent size of the absorbing inclusion. %G English %2 https://hal.science/hal-00741034/document %2 https://hal.science/hal-00741034/file/AOCT_holographic_detection%20scheme.pdf %L hal-00741034 %U https://hal.science/hal-00741034 %~ UPMC %~ ESPCI %~ CNRS %~ PARISTECH %~ IL %~ L2C %~ LANGEVIN %~ PSL %~ MIPS %~ UNIV-MONTPELLIER %~ SORBONNE-UNIVERSITE %~ SU-INF-2018 %~ SU-SCIENCES %~ UP-SCIENCES %~ ESPCI-PSL %~ SU-TI %~ ALLIANCE-SU %~ UM-2015-2021
