Paper Abstract

The function structure and angle solution algorithm of a novel imaging polarization navigation sensor are proposed. The lab setup prototype of imaging polarization navigation sensor is constructed, and the photo response of dual-tier polarization grating is given. A novel angle solution algorithm for imaging polarization navigation is designed, which implements precise navigation angle extraction by means of main polarization direction selection, polarization direction line character detection and polarization direction image center checkout. Combined polarization light sensitivity wave band with broad vision field polarization direction imaging detection, the detection spatial solution of polarization navigation sensor can be effectively improved. Polarization grating photo response and polarization image direction detection experiment indicates the function structure design and angle algorithm of the novel polarization navigation sensor are feasible.
