In the laser warning system, a non-mechanical scanning Fabry-Perot (F-P) type laser warning method and its crucial component-laser
incident sensor design method are brought out, and the F-P etalon with the interferometric filter combination is adopted.
For the incident laser pulse with a certain wavelength, the transmittance difference of the interferometric filters is independent
with polarization of incident light, and descends almost linearly as the incident angle gets wider. A laser incident angle
sensor experimental platform is built up, and the experiment is carried out with a given laser range finder. As the results
indicate, when the incident angle is less than 5°, the transmittance difference measured by the laser angle sensor is significantly
lower, and the deviation is more than 10%. While the incident angle is greater than 10°, the deviation is reduced significantly. 相似文献
