摘要

An addressable array of lenses is disclosed. Two electrical connections per row address specific lenses within that row. Carriages support individual lenses, thus forming resonant units with frequencies unique within each row. A voltage, having the same frequency as a selected resonant unit is applied. The selected lens produces a resonating image. Testing has verified proper resonance addressing within a 5-by-5 array of microlenses. The array can be applied to a Shack-Hartmann (SH) sensor. To compensate for errant images formed outside of their image area, resonating images are identified by a processor. The array thus improves the dynamic range of the wavefront aberration that can be measured by an SH sensor. The inventors currently estimate the improvement over conventional designs to be about a factor of 30.
