Efficient 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 کاملHigh Precision Signal Processing Algorithm for White Light Interferometry
A new signal processing algorithm for absolute temperature measurement using white light interferometry has been proposed and investigated theoretically. The proposed algorithm determines the phase delay of an interferometer with very high precision (.
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 کاملBasics of White-Light Interferometry
Interferometer Setup The Twyman–Green interferometer (Figure 1) is a special configuration of the well-known Michelson interferometer with optics that superimpose the images of the object and the reference planes. Polytec engineers use this interferometer and place a CCD image sensor like those used for digital photography at the point where the two images are superimposed. A broadband “white-l...
متن کاملMoiré interferometry with white light.
While high-sensitivity moiré interferometry requires monochromatic light, an auxiliary compensator grating removes the requirement. Experimental verification utilized white light for moiré interference of sensitivity 0.833 microm/fringe. Configurations readily amenable to compensation include moiré fringe multiplication by even factors and the minimum-deviation arrangement. Chromatic compensati...
