This is a simple but universal calculation of optical diffraction. With "pattern" selected, you can see well-known diffraction patterns. You can change the gap size of the slit, the screen position, and the wavelength of the light to be diffracted. These three parameters cover most situations of light diffraction by a single slit. When "profile" is selected, you can see the intensity plot according to the screen surface. When "clothoid" is selected, you can see the clothoid, also known as the Euler or Cornu spiral.
