摘要
目的 :解决近距离观察用便携式视频单筒望远镜的照明问题。方法 :定制适合近距离观察用便携式视频单筒望远镜的发光灯头和反光灯头,将发光灯头后置式安装在物镜不能承重的目镜端,将发光灯头或反光灯头前置式安装在物镜能够承重的物镜端,分别使用安装照明系统和未安装照明系统的望远镜观察新鲜火龙果的创腔。结果:安装了定制的发光灯头和反光灯头的望远镜照明充足,无论创腔是浅表还是深远,无论倍率是低倍还是高倍,视屏图像均明亮,能够清楚分辨瓤籽。结论:近距离观察用便携式视频单筒望远镜能够低成本安装光线充足的照明系统,或可在颅脑显微手术中发挥作用。
Objective To solve the problems in the illumination of the portable video monocular telescope for near-obser-vation.Methods Some luminous lamp head and reflective lamp head were customerized for the telescope, and the lumi-nous lamp head was postpositively mounted at the side of the ocular lens, which or the reflective lamp head could be prepositively mounted at the side of the object lens. A wound pit on fresh pitaya was observed using portable video monocular telescope for near-observation equipped with illumination device or not. Results Luminous lamp head and re-flective lamp head custom-made was able to mount easily and gave the target ample illumination. Conclusion Portable video monocular telescope for near-observation can be easily and cheaply equipped with luminous device giving ample il-lumination.
