Unwin's Construction of an Involute Spur Gear
editUnwin's Construction is a method of drawing a close approximation to an involute gear tooth. There are 8 images in the series and a complete description of the method can be found on the page Unwin's Construction.

Density Plots
editThese density plots are highly detailed and need to be veiwed at full resolution for best effect. The images here are half-size. The wavlegnth is 800nm, and the slit separation is 0.1mm.
Two Slits
editThe wave near the slits (0.15mm across by 0.075mm high). This is looking down at the the wave at t=0.
This the same area, but averaged over a full cycle, to reveal the finging pattern
Further out (200mm across by 5 metres high). There are a lot of distortion and false patterns due to moiré and beat frequencies between the wave's frequency and the pixel/sampling frequency of the image/plotting.
Averaging over a full cycle reveals the simple fringe structure:
