According to Kieran G. Larkin, interferogram analysis finds its roots in the 1960's from Carre Rowley and Hamon.  Analysis methods can be sorted into two main categories: "temporal (phase shifting) methods and spatial methods."  The methods of Carre, Rowley and Harmon lie in the range of temporal methods.  This form of analysis was problematic in that the phase shift needed to be precisely calculated (i.e. a larger degree of experimental control must be present).  This ushered in the wave of spatial analysis methods which took advantage of the lack of need of multiple fringe patterns to analyze.  With experimental control increasing and computing power also increasing methods of the present usually are computationally involved or have a mixture of the control of the lab and the computer.  The list below of analysis methods only represents a fraction of the variations of interferogram analysis (i.e. this list should not be considered exhaustive, but rather an overview of the main classes of analysis methods).
