Description
Imaging surveys such as the Dark Energy Survey and LSST record the positions,
shapes, magnitudes, and colors in a few filter bandpasses of 0.6B to 4B
galaxies. Precision redshifts of hundreds of millions of galaxies are enabled
by technologies that allow of to accumulate photons from thousands of
individual objects in parallel. More cost-effective, smaller-scale optical
fiber positioners will provide increases in multiplex power that are needed
for Stage V dark energy research. I will describe the present
state of robotic fiber positioner technologies and outline the direction
and goals for current R&D.
