Richard Wheeler (who recently reconstructed a lightning bolt using Blender), now uses a microscope to reconstruct a resistor of 0.8 x 0.3 mm. Blender was used in the visualization.
3D scanning is a very powerful tool, and it's value isn't limited to the objects and scenes you interact with in everyday life. The ability to precisely determine the 3D shape of tiny (even microscopic) objects can also be really useful.
The 3D reconstructed shape of a tiny (0.8 by 0.3 mm) surface mount resistor on a printed circuit board. This was made using only a microscope; no fancy laser scanning required!
3D scanning through a microscope is a bit different to normal 3D scanning; mostly because when you look down a microscope at an object it looks very different to what you might expect from day-to-day life. The most immediately obvious effect is that out of focus areas are very out of focus, often to the point where you can barely see what is there. This effect comes down to the angle over which light is collected by the lens capturing the image; your eye or a camera lens in everyday life, or an objective lens when using a microscope.
