At the moment (Oct 2007) the next three SVGs do not render correctly, as they use the Inkscape blur feature which is not supported. However, hopefully it will be soon.

[edit] Unwin's Construction of an Involute Spur Gear

Unwin'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.

[edit] Density Plots

These 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.

[edit] Two Slits

The wave near the slits (0.15mm across by 0.075mm high). This is looking down at the the wave at t=0.

$Two-Slit Diffraction (close up)$

This the same area, but averaged over a full cycle, to reveal the finging pattern

$Two-Slit Diffraction (close up average)$

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.

$Two-Slit Diffraction (distant)$

Averaging over a full cycle reveals the simple fringe structure:
