求翻译：光学双稳器件种类繁多，除了按反馈方式和非线性机制分类之外，还可以分为有腔型(包括有源型和无源型)和无腔型（包括单镜型和无镜型）等，如图5.1.8所示。单反射镜的光学双稳器件只靠一次反馈作用产生光学双稳性；无反射镜的光学双稳器件则是靠介质内部的反馈机制。在5.2.3节和5.3.4节将会分别介绍一些全光型的与混合型的特殊器件。是什么意思？

Optics bistable component type is many, besides presses the feedback way and the non-linear mechanism classification, but also may divide into has the cavity (including active and passive) and does not have the cavity (including single-mirror and does not have mirror) and so on, as shown in Figure 5
