Abstract
The pursuit of high-precision and high-efficiency phase recovery methods has been a research focus of interferometric technology. We propose a dual-frame phase-shifting interferogram phase recovery technique based on normalization of the first-order norm. A set of sine and cosine components is constructed by the addition and subtraction of dual-frame interferograms. Then the first-order norm normalization method is employed to achieve vector orthogonality. The phase distribution is then obtained through the arctangent operation. State-of-the-art dual-frame phase recovery techniques are evaluated, and it shows that the first-order norm normalization method outperforms the second-order norm normalization method. Especially in terms of computational efficiency, the method using the first-order norm is at least 50% more efficient than other methods.
