A fully working caliper that uses a Moire pattern to reach a precision better than 0.05 mm. The accuracy should be better than 0.5mm.
No batteries, no electronics, no gears... It's just a couple of images sliding one on top of the other. The two images have been mathematically designed to display a Moire pattern shaped like an "indicator triangle": the tip of the triangle will indicate the sub-millimeter measurement.
Simply read the cm and mm on the main scale, and then the sub-millimeter value on the Moire scale.
