近红外偏振探测器校正方法
Calibration method for NIR polarization detector
摘要
Abstract
In this paper, a new NIR polarization detector is presented.It is fabricated out of a wire grid polarizer attaching to the surface of a FPA.A brand new method solving linear polarization is proposed at the same time.The transmittance and the angle of the wire grid are corrected.The effect on the de-gree of linear polarization ( DoLP) measurement is also eliminated in this report.Theoretically, the in-frared polarized image quality is independent of the transmittance and angle of wire grid.The experi-ment uses a blackbody source as the calibration light.The results show that, while ignoring the crosstalk between the polarized pixels, the measured value is about 14％～24％of the true value.After adding the transmittance correction, the data reaches the level of 80％～120％while it becomes 96％to 104％by applying the angle correction.关键词
