The meaning of PRINCIPAL AXIS is the line with respect to which a spherical mirror or lens system is symmetrical and which passes through both the center of the surfaces and their centers of curvature.
principal axis n 1.(General Physics) the line passing through the optical centre and centres of curvature of the faces of a lens or a curved mirror 2.(General Physics) any of three mutually perpendicular axes about which the moment of inertia of a body is maximum ...
A heliostat carrying a number of mirrors has one principle axis of rotation which permits slow movement to follow the sun in azimuth. Each individual mirror has a secondary axis enabling them to turn slowly to follow elevation of the sun. A heliostat comprises a frame with a single axis of ...

In the presence of two or more non-orthogonal sets of vertical fractures, the symmetry of the medium may be approximated as monoclinic with a horizontal plane of mirror symmetry if, in the absence of fractures, the rock is transversely isotropic (TI) with the symmetry axis perpendicular to ...
In both cases, increasing the sample size did not alter the PCs (the y-axis flip between (C) and (D) is a known phenomenon). Full size image The case of different sample sizes The extent to which different-sized populations produce results with conflicting interpretations is illustrated ...
“principal axes”. The orthogonal vectors forming the flag mentioned above are called “weight vectors”, or “loadings”. Sometimes they are called “principal components”, although that term is sometimes used to refer to points projected onto a principal axis. In this post I stick to “PCA...

11 and 12, a beam emitted from a light source device 211 is bent by a returning mirror 217. In the main scanning section, the beam is incident on the polygon mirror 215 from a direction substantially corresponding to the optical axis of the scanning optical system 216 (front incidence). ...
