I’m currently working with one of my students on a laser-based range finder. To assess the precision of the device, I needed a calibration piece. Because of the setup, the piece should look like a stair.
The piece should allow a wide range of different readings, say from 1 to 10 centimeters in known increments, say, 1cm. The naïve way of building such a piece is to build a stair with 10 steps. However, if you do it like this, the piece is wide, cumbersomely so. Is there a much better way to do so?
