Mitigation Approaches for Optical Imaging through Clouds and Fog
Abstract
This report offers novel designs for active optical imaging through clouds and fog, motivated by many military applications, such as laser range-finder, target designation for seekers and laser radar. The report focuses on jointly-optimized wireless optical multi-input multi-output (MIMO) transceivers for through-clouds airborne active optical imaging systems. Photolithographic techniques are employed in designing the optical transceiver subsystems. Our design goal is to select the diversity receiver branches field-of-view (FOV) in a way that the effect of multi-scattering dispersion is reduced by as much as possible. The light beam is converted to multiple beams for transmission over several independent wireless optical channels. At the optical imaging receiver platform, combined received beams are photo-detected, and an electronic receiver is employed to recover the images. We demonstrate high-resolution imaging can be achieved with a high reliability everywhere within the coverage area.
