Abstract
The wave-front phase recovery method is a method of numerically calculating the phase distribution of the wave-front by measuring the field intensity distribution of the emission field. Because of its easy operation, high accuracy of inversion and high precision, it has received great attention and extensive application in the free-form surface shape in modern optics detection, telescope primary, secondary mirror misalignment detection and adjustment, beam shaping and other fields. This article briefly describes several different classical methods for restoring the wave-front phase, such as the GS algorithm, HIO algorithm, and PIE algorithm in the iterative method; The transport of intensity equation (TIE)method in the non-iterative method. Then analyzed their respective advantages and disadvantages, at same time put forward personal opinions on the current deficiencies and the future direction of development.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
