The precision in time of light exposure requires the optical shutter in an optical system to work with high-speed response and rapid change between close/open state, however, a motor-driven system cannot attain perfect accuracy due to the system response. This is the unsolvable problem that comes when designing an optical shutter; and with different methods to approach the problem, many types of shutter with various parameters have been built. The most popular optical shutters now in the market are made by Thorlabs with acceptable responses to the controller but they are very expensive. In this paper we have developed an optical shutter system using Arduino software and hard disk drive base, which is superior to some characteristic of Thorlabs' shutter (e.g transfer initialize, transfer open, minimum open pulse), but also much cheaper and can be widely manufactured.
