2D Light Field

The 2-dimensional light field data types provide a more convenient way to represent the light field in the plane space and can be used with our optical propagation methods.

OpticalPropagation.MonoLightField2D — Type
MonoLightField2D  <: AbstractLightField2D

MonoLightField2D is used to represent a 2-dimensional monochromatic light field.

Examples

julia> using Unitful

julia> MonoLightField2D([1 2; 3 4],wavelength=632.8u"nm",size=(1u"mm",1u"mm"))
MonoLightField2D:
    wavelength: 6.328e-7 m
    physical size: (0.001 m, 0.001 m)
    complex amplitude data:
2×2 Array{Complex{Float64},2}:
 1.0+0.0im  2.0+0.0im
 3.0+0.0im  4.0+0.0im

Work with Plots.jl

The 2-dimensional light field data types can work with Plots.jl, so it will be more convenient when we want to visualize a light field. For example,

using Unitful
using Plots

gauss = MonoLightField2D(
    [exp(-(x^2+y^2)/6400) for x in -200:199, y in -200:199],
    wavelength=632.8u"nm",
    size=(1u"mm", 1u"mm")
)
plot(gauss)
