Abstract
The paper is intended to be a review of fringe pattern analysis, FPA methods and their capabilities to analyze extended class of fringe patterns. The special emphasis is paid to the distinction between passive and active methods and the general trend to hybridization of the approaches in FPA. More detailed description is given to the general description of the most commonly used FPA methods, namely: temporal and spatial carrier phase shifting methods. Latter various approaches to absolute phase determination basing an application of additional means or modification of system parameters and including fringe numbering, phase unwrapping or hierarchical unwrapping are analyzed and compassed.
