Query: Fundamental Limits on Measuring the Rotational Constraint of Single
  Molecules using Fluorescence Microscopy   Optical fluorescence imaging is capable of measuring both the spatial and
rotational dynamics of single molecules. However, unavoidable measurement noise
will result in inaccurate estimates of rotational dynamics, causing a molecule
to appear to be more rotationally constrained than it actually is. We report a
mathematical framework to compute the fundamental limit of accuracy in
measuring the rotational mobility of dipole-like emitters. By applying our
framework to both in-plane and three-dimensional methods, we provide a means to
choose the optimal orientation-measurement technique based on experimental
conditions.
