我系研究了一种基于傅里叶频谱存贮原理的二次曝光新技术。采用脉宽和间隔可调的调制脉冲对激光光源即可对瞬态流场进行高速,多幅、动态全息干涉摄影。
I studied a new double exposure technology based on Fourier spectrum storage principle. Using pulse width and adjustable modulation pulse on the laser source can transient high-speed, multi-shot, dynamic holographic interference photography.
