We present an optical wavefront shaping approach that allows tracking and localization of a signal hidden inside or behind scattering medium. The method combines traditional feedback based together with switch function, controlled by two different signals. A simple, in transmission imaging system is used detectors: one monitors the speckle signature other tracks fully (e.g., fluorescent beads)....

A strategy for multiple removal consists of estimating a model of the multiples and then adaptively subtracting this model from the data by estimating shaping filters. A possible and efficient way of computing these filters is by minimizing the difference or misfit between the input data and the filtered multiples in a least-squares sense. Therefore, the signal is assumed to have minimum energy...

The flexibility of the mechanical system is one of the factors of the bandwidth limitation. Especially, it is known that an out-of-phase vibration mode makes the closed loop unstable with the negative feedback of the positioning error. In this paper, a novel mode shaping method for in-phase design of flexible structures is proposed. From the relation between the modal analysis and the state-spa...
