Bases: object

Represent the geometric specification of a bolometer sensor head or slit aperture.

The Geometry describes both simple rectangular / circular sensor faces and arbitrary polygonal / polyline definitions via explicit coordinates. It encapsulates a local orthonormal (or user supplied) basis, extents, and derived surface properties.

Methods

Attributes

`coords`	Coordinate array defining the outline in the `basis_x` and `basis_y` plane.
`dx`	Width along `basis_x` for rectangular geometry.
`dy`	Width along `basis_y` for rectangular geometry.
`radius`	Radius for circular geometry types.
`surface`	Precomputed surface area of the aperture face.
`type`	Enumerated shape type.
`centre`	Geometric centre (reference point) of the sensor/slit in global 3D coordinates.
`basis_x`	Local x-axis direction vector lying in the sensor/slit plane.
`basis_y`	Local y-axis direction vector lying in the sensor/slit plane.
`basis_z`	Local outward-facing normal vector perpendicular to the sensor/slit plane.

centre : Point3D¶: Geometric centre (reference point) of the sensor/slit in global 3D coordinates.

type : GeometryType = 3¶

Enumerated shape type.

Common values include RECTANGLE, CIRCLE, OUTLINE, etc. Defaults to GeometryType.RECTANGLE.

basis_x : Vector3D¶: Local x-axis direction vector lying in the sensor/slit plane.

basis_y : Vector3D¶: Local y-axis direction vector lying in the sensor/slit plane.

basis_z : Vector3D¶

Local outward-facing normal vector perpendicular to the sensor/slit plane.

This vector must be directed toward the radiation sources. When None, it can be derived as the cross product of basis_x and basis_y.

dx : float = 0.0¶

Width along basis_x for rectangular geometry.

None when not applicable (e.g., circular or polygonal types).

dy : float = 0.0¶

Width along basis_y for rectangular geometry.

None when not applicable (e.g., circular or polygonal types).

surface : float = 0.0¶

Precomputed surface area of the aperture face.

If None, may be derived from dx/dy (rectangles), radius (circles), or coords (polygons) during validation or runtime.

radius : float = 0.0¶

Radius for circular geometry types.

None if the geometry is not circular.

coords : ndarray[tuple[Any, ...], dtype[float64]] | None = None¶

Coordinate array defining the outline in the basis_x and basis_y plane.

This array is used to represent a complex geometric outline. The array shape is (2, N) where N is the number of points.
