Abstract
A method for imaging a surface includes generating a traveling lens in an acousto-optic material and incorporating a traveling mask into a portion of the traveling lens so as to produce a composite traveling lens. The method further includes irradiating the composite traveling lens so as to produce a composite focused beam having a spatial variation across the composite focused beam. The composite focused beam is directed onto a region of the surface so as to generate radiation characteristic of the region from the region. The radiation is imaged onto a detector so as to generate a signal characteristic of the region, responsively to the spatial variation.
