摘要 冷原子具有很小的速度,很窄的速度分布以及良好的相干特性,利用冷原子物质波干涉特性可实现原子干涉仪,具有萨格奈克效应的原子干涉仪即原子陀螺仪,可精密测量转动速率.冷原子轨迹的精确控制对提高冷原子陀螺仪的测量精度有着重要的意义,文章报道了利用直接数字频率综合器,实现对双向对抛冷原子运动轨迹的精确控制. Cold atoms possess low velocity,narrow velocity distribution as well as good matter wave coherence,thus they have been used to achieve cold atom interferometers.The interferometers with Sagnac effect form atom gyroscopes which can measure rotation rate accurately.Here we report our recent progress in building a projectile cold atom gyroscope.We achieve the accurate control of the bidirectional projectile cold atom motion through the use of a homemade direct digital frequency synthesizer.
