Design and application of three channel polarization imaging navigation sensor

According to the needs of the polarization mode information of the sky, a three channel imaging polarization navigation sensor is designed and implemented.The principle of polarized light measurement based on Stokes vector is studied,based on this principle to build the sensor.Write the program control software,heading angle can be output in real time,to solve the disadvantages that the general experimental device can not be measured in real time.Outdoor unit test experiment was carried out,the experimental results show that:The sensor outside heading angle measurement of the average error is 0.83 degrees,can output high precision navigation angle,can meet the needs of real-time testing,to provide a stable source of information for the next combination of navigation.
