hexrd.instrument.cylindrical_detector module
- class hexrd.instrument.cylindrical_detector.CylindricalDetector(radius=49.51, **detector_kwargs)[source]
Bases:
Detector2D cylindrical detector
A cylindrical detector is a simple rectangular row-column detector which has been bent in the shape of a cylinder. Inherting the PlanarDetector class except for a few changes to account for the cylinder ray intersection.
- property angle_extent
- angles_to_cart(tth_eta, rmat_s=None, tvec_s=None, rmat_c=None, tvec_c=None, apply_distortion=False)[source]
Transform angular coordinates to cartesian.
Parameters
- tth_etaarray_like
The (n, 2) array of n (tth, eta) coordinates to be transformed.
- rmat_sarray_like, optional
The (3, 3) COB matrix for the sample frame. The default is None.
- tvec_sarray_like, optional
The (3, ) translation vector for the sample frame. The default is None.
- rmat_carray_like, optional
(3, 3) COB matrix for the crystal frame. The default is None.
- tvec_carray_like, optional
The (3, ) translation vector for the crystal frame. The default is None.
- apply_distortionbool, optional
If True, apply distortion to take cartesian coordinates to the “warped” configuration. The default is False.
Returns
- xy_detarray_like
The (n, 2) array on the n input coordinates in the .
- property beam_position
returns the coordinates of the beam in the cartesian detector frame {Xd, Yd, Zd}. NaNs if no intersection.
- property calibration_flags_to_lmfit_names
- cart_to_angles(xy_data, rmat_s=None, tvec_s=None, tvec_c=None, apply_distortion=False, normalize=True)[source]
Transform cartesian coordinates to angular.
Parameters
- xy_dataTYPE
The (n, 2) array of n (x, y) coordinates to be transformed in either the raw or ideal cartesian plane (see apply_distortion kwarg below).
- rmat_sarray_like, optional
The (3, 3) COB matrix for the sample frame. The default is None.
- tvec_sarray_like, optional
The (3, ) translation vector for the sample frame. The default is None.
- tvec_carray_like, optional
The (3, ) translation vector for the crystal frame. The default is None.
- apply_distortionbool, optional
If True, apply distortion to the inpout cartesian coordinates. The default is False.
Returns
- tth_etaTYPE
