SUMMARY

The Cornu Spiral is a graphical representation of the Fresnel integrals, defined by the equations x = ∫₀ᵗ cos(π/2 v²) dv and y = ∫₀ᵗ sin(π/2 v²) dv, where t is implicit. This spiral is instrumental in calculating Fresnel diffraction, a key concept in optics. The term "cornu" translates to "horn," reflecting the spiral's resemblance to a ram's horn. The name honors the mathematician who contributed to its development.

What is cornu spiral?
 
Physics news on Phys.org
It is a plot of the fresnel integrals,
x=\int_0^t\cos\left(\frac{\pi}{2}v^2\right)dv, \ \ y=\int_0^t\sin\left(\frac{\pi}{2}v^2\right)dv
( x vs. y, with t implicit) It is used in a graphical technique of calculating fresnel diffraction.

"cornu"= "horn". A cornu spiral is so called because it resembles a ram's horn.
 
Actually, there really was a person named Cornu!
