Paper Abstract

The directional accuracy of bio-inspired polarized light compass mainly depends on the extinction ratio and transmittance of the polarized light sensor. This paper first analyzes the influence of structure parameters, such as grating period, duty cycle and depth of grating, on the extinction ratio and transmittance of the grating. Then, this paper proposes the design scheme of the grating array structure, and conducts a preliminary experimental verification of the strategy to demonstrate its effectiveness.
