速示器是典型的心理学测控仪器.速示器普遍存在的视场少、刺激呈现的时间精确度不够、光源的稳定性不足以及智能化程度不高等缺陷.为克服这些缺点,设计了以PC机、单片机和FPGA等构成的速示器控制系统,从而大大改善了这些不足.在此重点介绍单片机在设备中控制功能的应用.%Tachistoscope is one of the typical instruments in psychology. Tachistoscope has often some disadvantages. For example, it has less field-of-view, its time of showing stimulus is not enough accuracy, the stability of the light source is not steady, and its intelligence is not high and so on. In order to overcome these shortcomings, the control system which based on PC, microcontroller and FPGA is designed. Therefore it greatly improves these deficiencies. The control function's application of microcontroller in tachistoscope is focused on.
