光学镜头成像规则

光学镜头有两种 :凸透镜和凹透镜. 凸透镜成像规则是: 如果物体不在焦点之外, the inverted real image will present in other side of convex focus, 真实图像有三种: 减小尺寸, 相同尺寸, 并放大 .

如果物体距离较小, 图像距离会更大, 那么真实形象也会更大;

如果对象置于焦点内, 放大的虚像将呈现在凸面焦点的同一侧,

如果 Object distance 较大, the image distance will be bigger , 虚拟映像也更大; 凹透镜的作用是光是发射, 成像规则比凸透镜复杂得多.
