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.
