An optical system for remote sensing in the UV, visible, and NIR spectral ranges

In this work, we propose a high-resolution optical system for Earth remote sensing, operating at 200–3300-nm wavelengths and providing a 4$^\circ$ field of view. Parameters of the system's structural elements are calculated and presented. Dot charts of the spots of confusion for the center, intermediate zones, and the edge of the field are considered. Over most of the operating wavelengths, the optical system is shown to be diffraction-limited, which provides attaining the highest possible spatial resolution. This system is considered as a tool for monitoring of the Earth's surface and collection of information in the ultra-violet, visible and near infrared spectral ranges (200–3300 nanometers).
