The incoherent imaging system in its isoplanatic region is a linear light intensity system with invariance in space.

非相干成象系统在等晕区内是空间不变性的光强线性系统。

Each linear light source unit is displaced on the rotating body or moving body to alternately project images with each other.

各线性发光单元放置在旋转体或运动体上以相互交替地投射图像。

In this case, however, the light is polarised in a different linear direction for each eye, so as to match the polarisation of the two side-by-side projectors used to show the film.

With a different hole design, crystal fibres can do the opposite trick as well, spreading the light much more evenly across the width of the fibre and thereby reducing non-linear effects.
