The wedge-ring detector is useful in Fourier frequency analysis, and is widely used in industry. The drawback is that the detector only gives the global frequency distribution about a signal, whereas details of the local frequency information are not provided. A wedge-ring wavelet detector is designed and fabricated to overcome the shortcomings in this paper. Simulation and experimental results are given to testify the performance. Primary applications to automation detection and pattern recognition are presented.
