Local frequency and envelope estimation by Teager-Kaiser energy operators in white-light scanning interferometry.
In this work, a new method for surface extraction in white light scanning interferometry (WLSI) is introduced. The proposed extraction scheme is based on the Teager-Kaiser energy operator and its extended versions. This non-linear class of operators is helpful to extract the local instantaneous envelope and frequency of any narrow band AM-FM signal. Namely, the combination of the envelope and f...
متن کاملTeager-Kaiser Energy and Higher-Order Operators in White-Light Interference Microscopy for Surface Shape Measurement
In white-light interference microscopy, measurement of surface shape generally requires peak extraction of the fringe function envelope. In this paper the Teager-Kaiser energy and higher-order energy operators are proposed for efficient extraction of the fringe envelope. These energy operators are compared in terms of precision, robustness to noise, and subsampling. Flexible energy operators, d...
متن کاملEfficient nonlinear algorithm for envelope detection in white light interferometry
A compact and efficient algorithm for digital envelope detection in white light interferograms is derived from a well-known phase-shifting algorithm. The performance of the new algorithm is compared with that of other schemes currently used. Principal criteria considered are computational efficiency and accuracy in the presence of miscalibration. The new algorithm is shown to be near optimal in...
متن کاملBayesian Estimation for White Light Interferometry
In this thesis, a new approach for the reconstruction of height maps from scanning white light interferometry is presented. This method unifies the conventional steps of preand postprocessing within Bayesian inference. An adept formulation of the prior allows for the exact computation of the height estimate, obviating the need for stochastic sampling or simulation methods. In conventional surfa...
متن کاملOn The Use of Conjugate Teager-Kaiser Energy Operators with Matched Filters
This work presents the proof of concept of using energy operator theory based on the conjugate Teager-Kaiser energy operators in matched filters for signal detection in multipath fading channels. To do so, we consider signals in the space S(R) a subspace of the Schwartz space S−(R) in order to approximate the received signal. These functions obey to some specific properties as shown in this wor...
