计算机硬盘驱动器中的音圈马达被证明是光束的极好的机械快门。快门速度超过10 mm/ms，可以在10 μ以下切换聚焦光束。S的光圈尺寸可达32 mm。快门操作只需要1 兆瓦的功率。快门可以用正弦信号驱动，以高达100 赫兹的频率切换。该快门也适用于X射线应用。对于大多数类型的操作，基本上不需要对驱动器或致动器进行修改。
Voice-coil motors in computer hard disk drives are shown to make excellent mechanical shutters for light beams. Shutter speeds in excess of 10 mm/ms are attained, allowing switching of a focused beam in under 10 μs. Aperture size can be up to 32 mm. As little as 1 mW of power is required for shutter operation. The shutter can be driven with a sinusoidal signal to switch at up to 100 Hz. The shutter is also suitable for x-ray applications. Essentially no modification of the drive or actuator is required for most types of operation.
