Oversample Reconstruction Based on a Strong Inter-Diagonal Matrix for an Optical Microscanning Thermal Microscope Imaging System
|
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.
