rayoptics.elem.surface module

Module for optical surface related classes

Surface
Container of profile, extent, position and orientation information of the surface

DecenterData
Maintains data and actions to support 4 types of position and orientation changes.

DEC: pos and orientation applied prior to surface

REV: pos and orientation applied following surface in reverse

DAR: pos and orientation applied prior to surface and then returned to initial frame

BEN: used for fold mirrors, orientation applied before and after surface

Aperture

Circular

Rectangular

Elliptical

class InteractionMode(value)[source]

Bases: Enum

enum for different interact_mode specifications

Retained to restore old files

Deprecated since version 0.4.5.

Transmit = 1: propagate in transmission at this interface

Reflect = 2: propagate in reflection at this interface

point_inside(x, y)[source]

Returns True if the point (x, y) is inside the clear aperture.

Parameters:

x – x coodinate of the test point
y – y coodinate of the test point
fuzz – tolerance on test pt/aperture comparison, i.e. pt fuzzy <= surface_od

get_y_aperture_extent()[source]: returns [y_min, y_max] for the union of apertures

intersect(p0, d, eps=1e-12, z_dir=1.0)[source]

Intersect an Interface, starting from an arbitrary point.

Parameters:

p0 – start point of the ray in the interface’s coordinate system
d – direction cosine of the ray in the interface’s coordinate system
z_dir – +1 if propagation positive direction, -1 if otherwise
eps – numeric tolerance for convergence of any iterative procedure

Returns:

distance to intersection point s1, intersection point p

Return type:

tuple

Raises:

TraceMissedSurfaceError –

normal(p)[source]: Returns the unit normal of the interface at point p.

class DecenterData(dtype, x=0.0, y=0.0, alpha=0.0, beta=0.0, gamma=0.0)[source]
