We propose and experimentally demonstrate a cost-effective pilot carrier assisted direct detection scheme based on discrete multitone (DMT) modulation format. The cost of the proposed scheme can be substantially reduced by two ways. First, we use dis

In this paper, the technique of electronic sheraing speckle pattern interferometry with wide Audio-frequency driving vibration is used in non-destructive test of the multiply plywood structure. Test results show that we are able to evaluate promply t

In this paper, we present an ESSPI-based method for non- destructive testing of laminated composite using wide audio- frequency driving vibration. This method is simple to operate and has many advantages over other NDT techniques.© (2002) COPYRIGHT

A triple-probe array is intensively used for diagnosing electron temperature and density of edge plasma in tokamaks. Up to now, electron temperature Te has been calculated with the approximate relation Te≈Vd2∕ln2 in the constraint of Vd3⩾2Te, w
