High-resolution multispectral imaging with random coded exposure

For multispectral image acquisition in remote sensing, high spatial resolution requires a small instantaneous field of view (IFOV). However, the smaller the IFOV, the lower the amount of light exposure to imaging sensors, and the lower the signal-to-noise ratio. To overcome this weakness, we propose a new random coded exposure technique for acquiring high-resolution multispectral images without reducing IFOV. The new image acquisition system …
