全塑料光学生命探测仪关键技术研究

制作了单丝直径为250 μm、像素数为4096、长度为15 m的塑料光纤传像束. 研究表明: 原始图像经过该15 m长的光纤传像束后, 仍有25%保留, 完全可以满足图像目视观察或CCD图像采集的需要. 以此光纤传像束为核心部件, 分别设计、制作了目视式生命探测仪样机, 以及与CCD、图像采集卡、笔记本电脑一体化的智能型光学生命探测仪样机. 最后, 演示了该系统对被困人员搜救的有效性. 此系统不但可用于地震、矿难等场合被埋人员的搜索, 也可用于高压强电磁干扰环境、保密部门、易燃易爆等特殊场合的视频监视.

Key technology on all-plastic optical lifedetection instrument

Plastic fiber image bundle with 250 μ single fiber diameter, 4096 pixels, 15 m length is fabricated. The result indicates that 25% of the input image remains after it has translated though the 15m fiber bundle, which can meet the need of eye observation or CCD image capture. Based on the key component of image bundle, the eye observation life detection instrument prototype and intelligent life detection instrument prototype connected with CCD, image capture card and portable computer are designed and produced. The effectiveness of researching and rescuing the person from danger is demonstrated. The system can be used not only for researching and rescuing the buried person, but also for video monitoring some special occasions, such as strong electromagnetic interference environment, security department and explosive places.
