Definition. The principal axis of a mirror is the central line or axis of symmetry that passes through the center of curvature of the mirror. It is the primary axis along which the mirror's optical properties are defined and image formation occurs.

In geometry and linear algebra, a principal axis is a certain line in a Euclidean space associated with a ellipsoid or hyperboloid, generalizing the major and minor axes of an ellipse or hyperbola. The principal axis theorem states that the principal axes are perpendicular, and gives a constructive procedure for finding them.
30 Δεκ 2020 · The principal axes are fixed relative to the shape of the rigid body and they are invariant to the orientation of the body-fixed coordinate system used to evaluate the inertia tensor.
The Principals Axes are the three mutually perpendicular axes in a body about which the moment of inertia is maximized.
Definition. The principal axis is an imaginary line that runs through the center of a lens or mirror, extending both directions. It serves as a reference line for understanding how light rays behave when they pass through or reflect off the optical device, ultimately impacting image formation and properties of the resulting image.
Any rigid body has three principal axes, which are mutually orthogonal, or can be chosen to be so. If a body has an axis of symmetry then rotations about that axis will be dynamically balanced; in other words that axis is a principal axis.
A principal axis is an axis where the products of inertia vanish. Thus, the inertia matrix becomes purely diagonal. In the case of a three dimensional rigid body with the principal axes defined by x*,y* and z* and origin fixed to the mass center of the body, the products of inertia would be Ix*y* = Iy*z* = Ix*z* = 0.
