title: High-speed electromechanical shutter for vision research.
abstract: A low-cost and high-speed electromechanical shutter is described. The design makes use of a small magnet moving in a magnetic field and includes a specially developed electronic control for optimal operation. The opening and closing time of the shutter is below 200 microseconds with overall time for generating light flashes close to 1 ms.
