探测器是接收系统中的关键性元件,其性能好坏以及运用正确与否对整个接收系统的性能好坏起着决定性的作用。所以,在选用探测器时,一般都要经过再三权衡才最后确定。为加大测距机的作用距离并使之小型化,目前国内外许多激光测距机上,都采用了硅雪崩光电二极-前置放大器组件作为探测器。如荷兰的MT-18,英国的LP7,加拿大或美国的GVS-5,国产的85式手持激光测距机等等,都是采用硅雪崩光电二极管-前置放大器组件来
The detector is the key component in the receiving system, its performance is good or bad and the correctness of the application plays a decisive role in the performance of the entire receiving system. Therefore, the choice of detectors, usually after repeated weighs before finalizing. In order to increase the range of the range finder and miniaturize it, a silicon avalanche photodiode-preamplifier module is used as a detector on many laser range finders at home and abroad. Such as MT-18 in the Netherlands, LP7 in the United Kingdom, GVS-5 in Canada or the United States, a domestic hand-held laser range finder 85 and the like, all use a silicon avalanche photodiode-preamplifier assembly
