VerticalTilt#

class deeptrack.aberrations.VerticalTilt(*args: tuple[Any, ...], coefficient: PropertyLike[float | list[float]] = 1, **kwargs: dict[str, Any])#

Bases: Zernike

Zernike polynomial with n=1, m=-1.

This class represents a Zernike polynomial corresponding to a vertical tilt aberration. It introduces a linear phase variation across the aperture aligned with the vertical axis.

Parameters#

coefficient: PropertyLike[float or list of floats], optional: The coefficient of the polynomial. Default is 1.

Attributes#

n: int: The radial index of the Zernike polynomial (always 1 for VerticalTilt).
m: int: The azimuthal index of the Zernike polynomial (always -1 for VerticalTilt).
coefficient: PropertyLike[float or list of floats]: The coefficient of the polynomial.

Examples#

Apply a VerticalTilt Zernike phase aberration (n=1, m=-1) to a simulated fluorescence image:

>>> import deeptrack as dt

>>> particle = dt.PointParticle(z=1 * dt.units.micrometer)
>>> vertical_tilt_aberration = dt.VerticalTilt(coefficient=-10)
>>> aberrated_optics = dt.Fluorescence(
>>>     pupil=vertical_tilt_aberration,
>>> )
>>> aberrated_particle = aberrated_optics(particle)
>>> aberrated_particle.plot(cmap="gray")
