By using a ruby laser, the Pulse Laser Holography, for its high-speed, real time, full view and contactlessness, is used to carry out the fast diagnosis of the behaviour of the synthetic fibers filament during the yar-texturing process.

• 利用脉冲激光全息术的高速、实时、全场和非接触测量的特点,作者采用红宝石激光全息照相,实现了对合纤长丝成纱过程快速诊断的应用研究,复丝成纱超快过程不同瞬间的成纱状态被记录于全息图上。
