6.1 INTRODUCTION

As discussed in the previous chapters, reliable estimation of phase plays a

crucial role in the application of optical interferometric techniques. is

chapter introduces a phase estimation approach based on local polyno-

mial phase modeling. Essentially, the approach relies on approximating

the phase as a local polynomial, which transforms phase measurement

into a parameter estimation ...
