The Design And Experimental Analysis Of Photo-Electricity Test System For Polarization Navigation

The bionic polarization navigation is an novel navigation method that mimic the some insects in nature using the polarized light in the sky to navigate.It is one of the frontier and hot research in navigaton field.In order to verify the directional mechanism of polarization navigation and further build up high precision mode of polarization navigation,the photo-electricity system of polarization navigation is designed.And the experimental data is processed by using the polarization simultaneous model.The experimental result shows that the design of photo-electricity system is effective.1.The mechanism of how insects use the polarized light to navigate is elaborated by using the polarized visual system and path integration system of desert ant.2.Based on the once atmospheric Rayleigh scattering model,the stability of the polarization pattern in a particular moment and in a particular direction is analysed.The formula of the calculating the four polarization parameters is build up using Stokes vector.And the polarization image of the sky is preliminary analysed.3.The modules of the optic-electricity test system is designed by reference to the polarized visual system,including the photoelectric conversion module,signal processing module and data acquisition module. 4.The response model of the polarized-light sensor is derived.The two models of polarization navigation is analysed:the scanning model and the simultaneous model.The error source of polarization angle is modeled and simulated.At last the theoretical output of simultaneous model is simulated.5.The experiment is carried out using the test system.The change trend diagram of polarization direction angle is get by using the experimental data processed by the simultaneous model.
