gradoptics.optics.window
- class gradoptics.optics.window.Window(left_interface_x_position, right_interface_x_position, n_ext=1.000293, n_glass=1.494, diameter=0.137, eps=1e-15)
Bases:
gradoptics.optics.base_optics.BaseOpticsModels a medium with a refractive index between two parallel surfaces. Refraction is modelled using Snell’s law.
- __init__(left_interface_x_position, right_interface_x_position, n_ext=1.000293, n_glass=1.494, diameter=0.137, eps=1e-15)
- Parameters
left_interface_x_position – Position of the left interface along the x axis (
float)right_interface_x_position – Position of the right interface along the x axis (
float)n_ext – Refractive index of the external medium (
float)n_glass – Refractive index of the medium (
float)diameter – Diameter of the interfaces (
float)eps – Parameter used for numerical stability in the different class methods (
float). Default is'1e-15'
- get_ray_intersection(incident_rays)
Computes the times t at which the incident rays will intersect the object.
- Parameters
incident_rays – The incident rays (
Rays)- Returns
Times t (
torch.tensor)
- intersect(incident_rays, t)
Returns the rays reflected or refracted by the optical element.
- Parameters
incident_rays – The incident rays (
Rays)t – The times at which the incident rays will intersect the optical element (
torch.tensor)
- Returns
(
tuple) - Reflected or refracted rays (Rays) - A boolean mask that indicates which incident rays were reflected or refracted ― some rays may not bereflected or refracted for example, due to total internal reflection, which is not modelled at this point (
torch.tensor)
- plot(ax, s=0.1, color='lightblue', resolution=100)
Plots the optical element on the provided axes.
- Parameters
ax – 3d axes (
mpl_toolkits.mplot3d.axes3d.Axes3D)
