With an increasing need for worldwide counter-terrorism, security is becoming a top priority on the agenda of local governments. Governments has enforced patrols, security forces, and security equipments such as door frame detectors, screens and hand-held detectors in public places like railway stations and airports. The main purpose of these security equipments is to detect potentially dangerous...
In this paper we present an investigation into using the swept frequency excitation for the inductive metal sensor. The frequency sweep excitation mode allows collecting eddy current data at a wide range of frequencies. The Nyquist polar plot of the sensor response depends on the geometrical and physical proprieties of the detected object. In this work an analytical solution of the response function...
A new target detection algorithm based on the generalized optimization of contrast enhancement (GOPCE) is proposed in this paper. Using the measured POL-SAR data, we compare the performances of the new detector and several conventional detectors, showing the effectiveness of the proposed algorithm.
The design and development of a new fiber-optic sensor for measuring the velocity of a continuous material (also called a web) in material processing systems is described. The development of the proposed sensor is based on the dual beam laser Doppler velocimetry technique and the unique properties of different types of optical fibers. The developed sensor is capable of measuring the true web transport...
Land mine detectors, security metal doors that we all go through in buildings and airports, as well as metal mining detectors are just examples of metal detector use in our daily lives. In this paper we present a cost efficient, low complexity very low frequency (VLF) handheld reconfigurable metal detector (MD) design and implementation that has the capability of discriminating between various metal...
