How does an Automated Rating Solution for Steel Inclusions Work?

The rating of non-metallic inclusions (NMIs) to determine steel quality is critical for many industrial applications. For an efficient and cost-effective steel quality evaluation, an automated NMI…

An Introduction to Computational Clearing

Many software packages include background subtraction algorithms to enhance the contrast of features in the image by reducing background noise. The most common methods used to remove background noise…

钢材质量评估过程中人工评级非金属夹杂物(NMI)的挑战

快速、精确和可靠的非金属夹杂物(NMI)评级对钢材质量评估具有重要作用。在钢铁生产和组件制造过程中,非金属夹杂物(NMI)人工评级是一种常用的方法.

学习如何从共聚焦图像中去除自发荧光

了解自发荧光的常见原因以及如何将其从共聚焦显微镜图像中去除。根据应用的不同,自发荧光的来源可能有很多种,但幸运的是,同样也有很多的解决方案--从更换介质到使用荧光寿命成像和近红外染料。

通过光遗传和电刺激技术研究纳米桥接结构和动力学

纳米级超微结构信息通常是由经固定和处理样品的静态图像获得的。但是,这些静态图像只是不断变化的动态结构中的一个瞬间。因此,如何探索动态过程中的特定时间点,是纳米级超微结构研究的一个重大挑战。通过光遗传或电刺激技术,并结合毫秒级样品玻璃化技术探索纳米级超微结构,是一种解决上述问题具有前景的技术。在本应用白皮书的第一部分中,我们将从实际应用角度讨论光刺激辅助的样品玻璃化工作流程。

Real Time Images of 3D Specimens with Sharp Contrast Free of Haze

THUNDER Imagers deliver in real time images of 3D specimens with sharp contrast, free of the haze or out-of-focus blur typical of widefield systems. They can even image clearly places deep inside a…
