ring detector

The decay time constant is larger than that of hot electron ring. This is conformed with results measured by use X-ray detector.

谱的发射，而在热电子环破裂之后，冷等离子体的衰减时间常数比热电子环的衰减时间常数大，这与X射线方法测量的结果是一致的。

In this paper, the characteristics of wedge ring detector ( WRD) are introduced. The correcting method of the responding factor is discussed theoretically, and the experimented results are given.

本文介绍了楔环阵列探测器（WRD）的特性，理论上论述了WRD线性响应因子校正的方法，并从实验上获得验证。

The CGH/ WRD system ( computer generated hologram/ wedge-ring shaped detector) were synthesized with CGH and CCD devices.

提出用计算机制全息图配合CCD器件制成具有楔环探测器功能的CGH/WRD系统。

We built, with our hands, a set-up of particle sizer with an all-solid-state Nd: YAG laser replacing the more conventional large-frame He-He laser, and a linear CCD array instead of the traditional concentric semi-ring shaped photoelectric detector.

采用全固态倍频Nd：YAG激光器取代传统的He-Ne激光器作光源，以一维线阵CCD取代传统的同心环光电探测器作为光信号探测器，自行搭建起一套测量微粒粒径分布的光电实验装置。
