A method of acquiring sequentially time-resolved two-dimensional images with parallel multi-group sampling strategy has been developed. In this technique, the two-dimensional image was sampled and transferred by a fiber bundle, the fibers of which were arranged in two-dimensional arrays in the input end and rearranged in four one dimensional lines in the output end. The output four groups of one-dimensional images were parallelly detected by a streak camera. The recorded images of the streak camera were then reconstructed according to the spatial relationship of the fibers between the input and output ends to obtain sequentially time-resolved two-dimensional images. The fiber bundle was composed of 64 64 pixels in the input end and four columns of 1 1024 pixels in the output end. Each pixel consisted of 4 4 fibers. The imaging system with about 10 ps temporal resolution has been applied for observing the flight of light, indicating that this technique can be a promising tool for investigating ultrafast phenomena.
已经开发出一种采用并行多组采样策略顺序获取时间分辨二维图像的方法。在该技术中，二维图像由光纤束进行采样和传输，光纤束的光纤在输入端排列成二维阵列，在输出端重新排列成四条一维线。输出的四组一维图像由条纹相机并行检测。然后根据输入端和输出端之间光纤的空间关系对条纹相机记录的图像进行重建，以获得顺序时间分辨二维图像。光纤束在输入端由64×64像素组成，在输出端由四列1×1024像素组成。每个像素由4×4根光纤组成。具有约10 ps时间分辨率的成像系统已被用于观察光的传播，这表明该技术可能是研究超快现象的一种有前途的工具。
