optika

A Python package for simulating and designing optical systems.

Functions

shape(a)	Return the array shape of the given object.
direction(angles)	Given a 2D vector of azimuth and elevation angles, convert to a 3D vector of direction cosines.
angles(direction)	Convert a 3D vector of direction cosines to a 2D vector of azimuth and elevation angles.

Modules

mixins	Mixin classes used throughout this package.
vectors	Vector types used throughout this package.
targets	Test targets for visualizing the performance of optical systems.
rays	A representation of light rays propagating through an optical system.
propagators	Simulate light propagating through an optical system.
metrology	Simulate the measurement and tolerancing of optical surfaces.
sags	The shape of an optical surface used to direct and focus light.
chemicals	A subpackage for retrieving optical constants of various chemicals.
materials	Simulate the interaction of light with transparent or reflective materials.
apertures	Apertures that can be used by optical surfaces to block a portion of the beam.
rulings	Periodic rulings which can be added to an optical surface to model a diffraction grating.
surfaces	Optical interfaces used to focus light.
sensors	Image sensors used to measure the light intensity at the output of an optical system.
distortion	Model the distortion of a scene observed by an optical system.
radiometry	Model the radiometry of an optical system.
systems	Optical systems consisting of multiple optical surfaces.
