Convex lens imaging

A lesson ( force ) of concept and a lesson ( convex lens imaging ) of scientific inquiry .

一节概念课（力），一节科学探究课（凸透镜成像）。

Two kind of simple methods , which are termed of extender lens amplification imaging method and convex lens amplification imaging method , are proposed based on amplification principle in this paper .

文中提出了两种利用放大原理测量全息光栅光栅常数的简单方法：扩束镜放大成像法和凸透镜放大成像法。

The system was mainly composed of the laser , the coating reflector , convex lens ( imaging objective lens as well ), imaging eye lens , zoom lens , CCD sensor , the data acquisition card and the computer .

该系统主要由激光器、镀膜反射镜、激光聚焦镜（同时也是成像物镜）、成像目镜、变焦透镜、CCD传感器、数据采集卡以及计算机等部件组成。
