摘　　要：激光全息实验中稳定度的问题一直是一个难以避免的难题,本次实验把压力传感器引入激光全息实验中,并设计了相关的控制程序,可以实时监控、实时调整激光全息干版的稳定度,经实验验证,取得了很好的效果,节省了拍摄的时间,由原来的1～2 d减少到现在的0.5～1.5 h,使全息图拍摄的成功率提高到90%以上。The stability is an important problem in taking laser holography of a scene.To monitor the stability of the holographic plate,pressure sensors ware introduced in our experiment.With the designed system and the program deveoped,real time monitoring and adjusting of the holographic plate is realized.Good result is achieved.Holograms taking time is shortened from 1～2 days to present 0.5～1.5 hours and success rate in creased to 90%.
