ABCDMatrixOptics.jl

This package implements the linear tracing of simple optical systems based on the Ray transfer matrix analysis. The convention of the optical elements is identical to those on Wikipedia.

Simple Example

A simple 4f re-imaging system with a magnification of 2 can be expressed as:

using ABCDMatrixOptics

# create needed optical elements
f1 = FreeSpace(200)
l1 = ThinLens(200.0)
f12 = FreeSpace(200 + 400)
l2 = ThinLens(400.0)
f2 = FreeSpace(400)

# simple, single ray
beam = GeometricBeam(w=10.0, k=0.1)

# create optical system
# it's built from left to right.
M = [f1, l1, f12, l2, f2]

# apply the system to the beam
# The matrices are evaluates as f2 * l2 * f12 * l1 * f1 * beam
# * is syntactic sugar for propagate
beam_p = M * beam
GeometricBeam{Float64}(-19.999999999999996, -0.05000000000000001, 1200.0)
# beam is magnified by 2 in size


# GaussianBeam
red_beam = GaussianBeam(w0=5e-3)
blue_beam = GaussianBeam(w0=5e-3, λ=405e-9)

using Plots

plot(M, red_beam)
plot!(M, blue_beam)
