Measurement of Displacement and Its Derivatives from a Phase Fringe Pattern
Pramod Rastogi, Rishikesh Dilip Kulkarni
Noting the fact that the phase and phase derivatives carry the information on the mechanical deformation in optical interferometric measurements techniques, we propose a noise robust fringe analysis technique for the simultaneous estimation of unwrapped ph ...
SPRINGER INTERNATIONAL PUBLISHING AG2019Simultaneous estimation of unwrapped phase and phase derivative from a closed fringe pattern
Pramod Rastogi, Rishikesh Dilip Kulkarni
We propose a new approach for the direct estimation of the unwrapped phase from a single closed fringe pattern. The fringe analysis is performed along a given row/column at a time by approximating the phase with a weighted linear combination of linearly in ...
2016Phase estimation from noisy phase fringe patterns using linearly independent basis functions
Pramod Rastogi, Rishikesh Dilip Kulkarni
A novel technique is proposed for obtaining unwrapped phase estimation from a highly noisy exponential phase field. In this technique, the interference phase is represented as a linear combination of linearly independent and pre-defined basis functions alo ...
