Since the first ion imaging experiment [D. W. Chandler and P. L. Houston, J. Chem. Phys. >87, 1445–1447 (1987)], demonstrating the capability of collecting an image of the photofragments from a unimolecular dissociation event and analyzing that image to obtain the three-dimensional velocity distribution of the fragments, the efficacy and breadth of application of the ion imaging technique have continued to improve and grow. With the addition of velocity mapping, ion/electron centroiding, and slice imaging techniques, the versatility and velocity resolution have been unmatched. Recent improvements in molecular beam, laser, sensor, and computer technology are allowing even more advanced particle imaging experiments, and eventually we can expect multi-mass imaging with co-variance and full coincidence capability on a single shot basis with repetition rates in the kilohertz range. This progress should further enable “complete” experiments—the holy grail of molecular dynamics—where all quantum numbers of reactants and products of a bimolecular scattering event are fully determined and even under our control.

Chem。物理> 87 ，1445-1447（1987）]，展示了从单分子解离事件收集光碎片图像并分析该图像以获得碎片的三维速度分布，功效的能力。离子成像技术的应用范围和广度不断提高和增长。加上速度映射，离子/电子质心和切片成像技术，其多功能性和速度分辨率已无法匹敌。分子束，激光，传感器和计算机技术的最新改进允许进行更高级的粒子成像实验，最终我们可以期望具有单方差的协方差和完全重合能力的多质量成像，重复频率以千赫兹为单位范围。这一进展将进一步实现“完整”的实验（分子动力学的圣杯），在该实验中，所有反应物的量子数量和双分子散射事件的产物都将被完全确定，甚至在我们的控制之下。
