Abstract:
A new interferogram’s decoding method that minimizes an estimate error in phase shifting of interfering fronts in noise environment at interference fringe patterns is proposed. A mathematical technique is considered to solve transcendental equations with step-by-step arbitrary shifting. A necessary and sufficient criterion is shown to solve this problem using the proposed method in accordance with the values of the induced phase shifts and their quantities. A comparative analysis of the proposed method and the interferogram’s decoding algorithm is performed based on vector representation of a set of transcendental equations.

Key words:
interferogram’s decoding method, transcendental equations, phase shifts.
