Abstract
We present a simple design of a fast mechanical shutter for light beams using a low-cost personal computer loudspeaker. The shutter is capable of closing an aperture of 5 mm at a maximum speed of 1.7 mm/ms with a timing jitter of less than 10 μs. When combined with polarization optics, our device can also be used as an alterable switch and adjustable attenuator.Keywords
