Investigation of the compressive line sensing imaging system in a controlled hybrid scattering environment

Abstract

In recent years, the Compressive Line Sensing (CLS) active imaging scheme has been proposed for underwater imaging applications. This concept has been demonstrated to be effective in the 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. In this work, we studied the CLS imaging system in a hybrid environment consists of particle and turbulence induced scattering. A CLS prototype was used to conduct a series of experiments at the Naval Research Lab Simulated Turbulence and Turbidity Environment (STTE). The imaging path was subjected to various turbulence intensities and water turbidities. The adaptation of the CLS sensing model to the hybrid scattering environment was discussed. The experimental results with different turbidities and turbulence intensities were presented.
