The landscape of biomedical research in neuroscience has changed dramatically in recent years as a result of spectacular progress in dynamic microscopy. In this context Adaptive Optics allows in-depth imaging by correcting aberrations induced by the biological sample, the key issue being then the ability to perform an accurate and reliable wavefront sensing (WFS). We present here a limitation of modal sensorless WFS in the case of a heterogeneous medium. We then build a new method called Axially-Locked Modal Sensorless (ALMS) that exploits these heterogeneities to overcome this limitation. The new method is simulated and compared to standard modal sensorless. The simulation results show a more accurate wavefront estimation even in the case of a strongly aberrated biological media.
