Methods Documentation

evolve_until(t)

Evolve the atmospheric layer until time t.

Parameters

tscalar

The time to which to evolve the atmospheric layer.

phase_for(wavelength)

Get the phase screen in radians at a certain wavelength.

Each atmospheric layer is modelled as an infinitely-thin phase screen.

Parameters

wavelengthscalar

The wavelength at which to calculate the phase screen.

reset()

Reset the phase screen.

This will create a randomized uncorrelated phase screen.
