Query: Stroboscopic Variation Measurement   A new procedure of the linear position measurement which allows to obtain
sensitivity better than the Standard Quantum Limit and close to the Energetic
Quantum Limit is proposed and analyzed in details. Proposed method is based on
the principles of stroboscopic quantum measurement and variation quantum
measurement and allows to avoid main disadvantages of both these procedures.
This method can be considered as a good candidate for use as a local position
meter in the ``intracavity'' topologies of the laser gravitational-wave
antennae.
