Compressive line sensing imaging system in a controlled hybrid scattering environment

In recent years, the compressive line sensing (CLS) active imaging scheme has been proposed for imaging applications over strong scattering medium. This concept has been demonstrated to be effective in the particle-induced scattering mediums and in the turbulence environment through simulations and test tank experiments. Nevertheless, in many atmospheric and underwater surveillance applications, the degradation of the visual environment may come from both particle scattering (turbidity) and turbulence. We study the CLS imaging system in a hybrid environment consisting of simultaneous particle and turbulence-induced scattering for the first time. A CLS prototype is used to conduct a series of experiments at the Naval Research Lab Simulated Turbulence and Turbidity Environment. The imaging path is subjected to various turbulence intensities and turbidities, which maintained stably over experiment duration. The adaptation of the CLS sensing model to the hybrid scattering environment is discussed. The experimental results with different turbidities and turbulence intensities are presented.
