Here we show how ultrafast mirror-symmetric photomechanical contractions in the frontal forward-facing left and right eye photoreceptors give Drosophila super-resolution 3D-vision. By interlinking multiscale in vivo assays with multiscale simulations, we reveal how these photoreceptor microsaccades - by verging, diverging and narrowing the eyes' overlapping receptive fields - channel depth information, as phasic binocular image motion disparity signals in time. We further show how peripherally, outside stereopsis, microsaccadic sampling tracks a forward flying fly's optic flow field to better resolve the world in motion. These results change our understanding of how insect compound eyes work and suggest a general dynamic stereo-information sampling strategy for animals, robots and sensors.}, publisher={Cold Spring Harbor Laboratory}, author={Kemppainen, Joni and Scales, Ben and Razban Haghighi, Keivan and Takalo, Jouni and Mansour, Neveen and McManus, James and Lego, Gabor and Saari, Paulus and Hurcomb, James and Antohi, Andra and et al.}, year={2021}, month={May} }
