光致动器具有不产生磁噪声和远距离接收能量等特点。提出了一种利用光热效应的新型微操作器。它由三根光纤组成。光纤的一端被切割成斜面，并涂上黑色。在光纤的末端，对入射光产生光热效应。这种效应使得纤维末端拉伸振动。它可以释放一个直径为2.5毫米的球和一个目前由光能保持的微透镜。并对光热振动的机理进行了探讨。
An optical actuator has some interesting characteristics, such as no generation of magnetic noise and receiving the energy remotely. A novel micromanipulator using photothermal effect is proposed. It consists of three optical fibers. One end of the fiber is cut for a bevel and painted with black color. A photothermal effect is occurred responding to the incident beam at the end of optical fiber. This effect makes the end of fiber stretching vibration. It can release a ball with 2.5 mm of diameter and a microlens currently held by light energy. The mechanism of photothermal vibration is also studied.
