Summary: | Dwell time plays a vital role in determining the accuracy and convergence of the computer-controlled optical
surfacing process. However, optimizing dwell time presents a challenge due to its ill-posed nature, resulting in nonunique solutions. To address this issue, several well-known methods have emerged, including the iterative,
Bayesian, Fourier transform, and matrix-form methods. Despite their independent development, these methods
share common objectives, such as minimizing residual errors, ensuring dwell time's positivity and smoothness,
minimizing total processing time, and enabling flexible dwell positions. This paper aims to comprehensively review
the existing dwell time optimization methods, explore their interrelationships, provide insights for their effective
implementations, evaluate their performances, and ultimately propose a unified dwell time optimization
