Query: Miniaturized Shack-Hartmann Wavefront-Sensors for Starbugs   The ability to position multiple miniaturized wavefront sensors precisely
over large focal surfaces are advantageous to multi-object adaptive optics. The
Australian Astronomical Observatory (AAO) has prototyped a compact and
lightweight Shack-Hartmann wavefront-sensor that fits into a standard Starbug
parallel fibre positioning robot. Each device makes use of a polymer coherent
fibre imaging bundle to relay an image produced by a microlens array placed at
the telescope focal plane to a re-imaging camera mounted elsewhere. The
advantages of the polymer fibre bundle are its high-fill factor,
high-throughput, low weight, and relatively low cost. Multiple devices can also
be multiplexed to a single low-noise camera for cost efficiencies per wavefront
sensor. The use of fibre bundles also opens the possibility of applications
such as telescope field acquisition, guiding, and seeing monitors to be
positioned by Starbugs. We present the design aspects, simulations and
laboratory test results.
