When a camera or sensor is in an environment of strong illumination or high background noise, scattering from the object, or glare, can be so high that the object can be obscured. Daniel et al. used an adaptive optics technique to manipulate the wavefront of a coherent light source illuminating an object, in this case a toy mannequin, and showed that the direction of scattered light from the object can be controlled. As the wavefront of the illuminating light is iteratively manipulated through a spatial light modulator, the glare is reduced and the image becomes clearer. The technique is general and could be applied to different scenarios such as sensing, microscopy, and other demanding imaging tasks.
