Here, we are going to show a 2D recursive phase unwrapping system that unwraps the phase and cleans noise in the same process. This recursive phase unwrapping system behaves as an Infinite Impulse Response (IIR) system and we will show its stability and frequency analysis in 1D. The unwrapping results shown here, are compared with the well known least squares phase unwrapping method. The recursive phase unwrapping system shown here is robust to noise and it can be used to unwrap modulus 2π phase maps following simple row by row scanning strategies.
