Query: Weak measurement with a coherent state pointer and its implementation in
  optomechanical system   Weak measurement with a coherent state pointer and in combination with an
orthogonal postselection can lead to a surprising amplification effect, and we
give a fire-new physical mechanism about the weak measurement in order to
understand this effect. Moreover, this physical mechanism is a general result
and based on it, we present a scheme of optomechanical system to implement weak
measurement amplification on an orthogonal postselection.
