另一种工作原理是梯度折射率透镜(GRIN透镜),其厚度通常是恒定的,而折射率在径向方向上变化。 也可以(但不常见)结合这两种操作原理,即制造具有曲面的GRIN镜片。 典型的GRIN镜片具有圆柱形杆形,尽管可以有多种其他形状。 光学特性 例如,图1显示了光线的传播(根据几何光学),这些光线在GRIN透镜中偏转,如果镜头经过优化...
Gradient-index (GRIN) lens fabrication employing laser pulse width duration control, and related components, systems, and methods are disclosed. GRIN lenses can be fabricated from GRIN rods by controlling the pulse width emission duration of a laser beam emitted by a laser to laser cut the GRIN...
Fig. 1 GRIN lens Conventional spherical lens The GRIN lenses are produced by silver ion exchange in a special glass. The composition of the glass is protected by a patent. In contrast to the conventionally used technology this is a non-toxic process and bears no health and environmental...
Figure 1 shows a gradient index rod (GRIN rod) with the length of one full sinusoidal path, or one “pitch.” Figure 1 A GRIN rod, one “pitch” long. Shortening the rod to a length of 1/4 pitch, as shown in Fig. 2, forms a lens with a focal length of Figure 2 The gradient...

This report focuses on a design method for gradient index (GRIN) lens antennas with controllable aperture field distributions. First, we derive differential equations representing optical paths in a gradient index medium with two optical surfaces by using geometrical optics, and then we formulate a no...
