| Abstract: | Based on a strong inter-diagonal matrix and Taylor series expansions,an oversample reconstruction method was proposed to calibrate the optical micro-scanning error.The technique can obtain regular 2 × 2 microscanning undersampling images from the real irregular undersampling images,and can then obtain a high spatial oversample resolution image.Simulations and experiments show that the proposed technique can reduce optical micro-scanning error and improve the system's spatial resolution.The algorithm is simple,fast and has low computational complexity.It can also be applied to other electro-optical imaging systems to improve their spatial resolution and has a widespread application prospect. |
