a review on OCT optimization algorithms

the topic includes:

K-linearization

1. adding a prsim

2. NUDFT

3. NFFT (a very smart way, quick and almost simliar performance as NUDFFT)

4. zero crossing

5. zero crossing to initialize Auto Spectral Calibration (an iterative way to fit the curvature of the non-linear unwrapped phase)

6. Total Variance for NUDFT (this one shows the best results till now)

Doppler methods:

1. conventional

2. filtering in lateral

3. speckle

4. zero crossing (like STFFT for time domain)

lateral flow esitimation:

1. lateral correlation (Ruikang Wang)

2. speckle analysis
