We report on the implementation of a confocal microscopy system based on a 2.9 THz quantum cascade laser source. Lateral and axial resolutions better than 70 μm and 400 μm, respectively, are achieved, with a large contrast enhancement compared to the non-confocal arrangement. The capability of resolving overlapping objects lying on different longitudinal planes is also clearly demonstrated.
我们报告了基于2.9太赫兹量子级联激光源的共聚焦显微镜系统的实现情况。横向分辨率和轴向分辨率分别优于70微米和400微米，与非共聚焦配置相比，对比度有大幅提高。同时还清晰展示了分辨位于不同纵向平面上重叠物体的能力。
