Adaptive optics full-filed OCT (FFOCT) with a transmissive liquid crystal spatial light modulator
(LCSLM) as wavefront corrector is used without strict plane conjugation for low order aberrations
corrections. We validated experimentally that FFOCT resolution is independent of aberrations and
only reduce the signal level. A signal based sensorless algorithm was thus applied for wavefront
distortion compensation. Image quality improvements by the wavefront sensorless control of the
LCSLM were evaluated on in vitro samples. By replacing the FFOCT sample arm objective with an
artificial eye used to train ophthalmologists, adaptive optics retinal imaging was achieved. In vivo
experiments using a liquid lens to correct focus and astigmatism are underway.
