We developed a modified Hoffman contrast technique with a 12 ns pulsed incoherent extended white-light source that enables an easily interpretable visualization of ablation plumes with high resolution, a large dynamic range, and color information. By comparison, a conventional dark-field setup with a slitlike laser light source provides large sensitivity but a small dynamic range, and it is difficult to interpret the filtered images.
我们开发了一种改进的霍夫曼对比技术,使用12纳秒脉冲非相干扩展白光源,能够以高分辨率、大动态范围和颜色信息轻松直观地显示消融羽流。相比之下,具有狭缝状激光光源的传统暗场设置具有高灵敏度但动态范围小,并且难以解读滤波后的图像。
