Paper Abstract

To enhance the performance of Fourier single-pixel imaging using lower data, we propose a non-uniform spectrum sampling for FSI instead of the traditional uniform spectrum sampling. The principle is deduced, and the corresponding simulations are conducted to verify and evaluate the performance of our strategy. Results show that non-uniform spectrum sampling for FSI is feasible. Meanwhile, compared with the traditional spectrum acquisition strategy, our strategy shows an advantage in measurement efficiency and high reconstruction image quality under the same sampling ratio. Our proposed strategy has a good application prospect in video acquisition, multispectral hyperspectral imaging or other high speed and high precision field.
