Underwater polarization imaging based on compressed sensing theory

The present paper gives an overview of some techniques for <span class="hit">underwater</span> optical <span class="hit">imaging</span>, which employ <span class="hit">polarization</span> technique and <span class="hit">Compressed</span> <span class="hit">Sensing</span> <span class="hit">theory</span>. The schematic diagram of system has been presented. <span class="hit">Imaging</span> principle formulas for this <span class="hit">imaging</span> technique have been derived <span class="hit">based</span> <span class="hit">on</span> <span class="hit">Compressed</span> <span class="hit">Sensing</span> <span class="hit">theory</span>. The relationship between the target reflection with backscattering and attenuation distance has been analyzed. The theoretical limit of detection distance of the technique is about 7.4AL.The techniques of <span class="hit">polarization</span> <span class="hit">imaging</span> and signal pixel camera have been combined for signal <span class="hit">Compressed</span> <span class="hit">Sensing</span> sampling. It has a higher application value of <span class="hit">underwater</span> <span class="hit">imaging</span> along with the perceived advantages of <span class="hit">polarization</span> <span class="hit">imaging</span> and <span class="hit">Compressed</span> <span class="hit">Sensing</span> sampling. &copy; 2015 Taylor &amp; Francis Group, London
