介绍了光参量振荡器在红外对抗技术中的应用背景和意义,同时时激光红外对抗的一些基本原理进行了讨论,给出了干扰激光能量的具体分析.用所研制的中红外 LiNbO_3-OPO,分别通过改变其输出波长和工作频率,对红外热像仪进行了干扰原理性实验.当干扰激光波长为3.8μm、重频20 Hz 时,成功使热像仪解除锁定.最后,对实验结果进行了分析和讨论.
The application background and significance of the optical parametric oscillator in the infrared countermeasure technology are introduced. Some basic principles of the laser infrared countermeasure are discussed at the same time, and the concrete analysis of the interfering laser energy is given.With the developed mid-infrared LiNbO_3-OPO, Respectively, by changing its output wavelength and operating frequency of infrared thermal imager interference principle experiment.When the interference laser wavelength of 3.8μm, repeat frequency 20Hz, the success of the thermal imager to unlock.Finally, the experimental results were carried out Analysis and discussion.
