中文摘要	为了实现对运动目标与天空散射光的偏振分布模式进行快速、有效的探测,根据连续旋转检偏器光强度透射的数学模型,利用光电传感器的积分特性,设计并构建了采用连续旋转检偏器的偏振成像探测装置。测试结果表明,该装置对偏振光的角度的测量精度优于0.069°(3σ),偏振度的测量精度优于0.12%(3σ)。一幅偏振图像的探测时间达到0.7 s。在偏振度低于4%的情况下,仍可以探测到有规律的偏振分布模式,其抵抗恶劣天气的性能优于现有的偏振导航探测装置。; In order to detect movement targets and scattered skylight polarization pattern rapidly and effectively,a detection system was constructed. Based on the light intensity transmission model of continuously spinning polarization analyzer,the detection instrument is designed by means of the integral characteristic of photoelectric devices. Performance test is implemented,measurement accuracy of polarization angle is better than 0. 069°( 3σ); Measurement accuracy of degree of linear polarization is better than 0. 12%( 3σ). The acquisition time of a series of light intensity images for one polarization image is achieved within 0. 7 s. In the situation that the skylight's degree of linear polarization is less than4%,the system can also detect the polarized pattern for navigation effectively. It can be used in bad weather condition and has better performance compared to the former instruments.
