Sequential Coaxial System¶

Optical system model¶

CoaxialRayTracing(surfaces[, sensor, ...])

A class of sequential and ray-tracing-based optical system model.

Point spread function models¶

There are various different ways to compute PSF of a CoaxialRayTracing model, each of which is represented as a subclass of CrtPsfModel. They implements the CrtPsfModel.psf() method to compute PSF of a given point.

`CrtPsfModel`([psf_size])
`CoherentKirchoffPsf`([psf_size, psf_center])
`CoherentHuygensPsf`([psf_size, psf_center])
`CoherentFraunhoferPsf`([psf_size])
`IncoherentRectKernelPsf`([psf_size, psf_center])
`IncoherentGaussianKernelPsf`([psf_size, ...])

Determining PSF center¶

`PsfCenterDeterm`()	A class to define the way to determine PSF center.
`LinearPsfCenter`()	PSFs are centered around ideal image points thus realistic distortion is simulated.
`FixedPsfCenter`(center)	PSFs are centered around the given coordinates in lens' coordinate system.
`ChiefRayPsfCenter`([wl_reduction])	PSFs are centered around the intersections of corresponding chief rays and image plane.
`MeanPsfCenter`([wl_reduction])	PSFs are centered around their "center of mass".
`RobustMeanPsfCenter`([wl_reduction, ...])	Similar to `'mean'` but iteratively computes center and then weeds out outliers.

Visualization¶

`CRTVisConfig`(color_fresnel, ...)	A data class describing visualization configuration for `CoaxialRayTracing`.
`CRTSpotDiagram`(fig[, rms, geo_radius])	A data class encapsulating the information about a spot diagram of `CoaxialRayTracing`.
