We present the application of wavefront sensing to three-component, three-dimensional micro particle tracking velocimetry (μPTV). The technique is based upon examining the defocus of the wavefront scattered by a tracer particle and from such informa

The magnetic storage capacity depends significantly on the area density, which is close related to the flying-height (FH) of magnetic head. In this paper a double common-path heterodyne interferometer is proposed to measure the FH. The resolution of
