This is commonly viewed using calcite crystals, which present the viewer with two slightly offset images, in opposite polarizations, of an object behind the crystal. It was this effect that provided the first discovery of polarization, by Erasmus Bartholinus in 1669. Of course the orientation of the x and y axes used in this description is arbitrary. The choice of such a coordinate system and viewing the polarization ellipse in terms of the x and y polarization components, corresponds to the definition of the Jones vector in terms of those basis polarizations. One would typically choose axes to suit a particular problem such as x being in the plane of incidence. Since there are separate reflection coefficients for the linear polarizations in and orthogonal to the plane of incidence , that choice greatly simplifies the calculation of a wave's reflection from a surface. Polarization is best understood by initially considering only pure polarization states, and only a coherent sinusoidal wave at some optical frequency. The vector in the adjacent diagram might describe the oscillation of the electric field emitted by a single-mode laser .
This causes circular birefringence, and is engineered so that there is a 90 degree rotation of the linear polarization state. However, when a voltage is applied across a cell, the molecules straighten out, lessening or totally losing the circular birefringence. On the viewing side of the display is another linear polarizing sheet, usually oriented at 90 degrees from the one behind the active layer. Therefore, when the circular birefringence is removed by the application of a sufficient voltage, the polarization of the transmitted light remains at right angles to the front polarizer, and the pixel appears dark. With no voltage, however, the 90 degree rotation of the polarization causes it to exactly match the axis of the front polarizer, allowing the light through. Intermediate voltages create intermediate rotation of the polarization axis and the pixel has an intermediate intensity. Displays based on this principle are widespread, and now are used in the vast majority of televisions, computer monitors and video projectors, rendering the previous CRT technology essentially obsolete.
Linear lighting is has become increasingly popular due to its flexibility, excellent performance and aesthetic appeal. Flexibility – linear lighting can be mounted into almost any ceiling type. You can get surface mounted, suspended, recessed and grid ceiling mounted. Some linear lighting products offer a range of connecting shapes in corner L shapes or T and cross junctions. These connecting shapes combined with a range of lengths allow lighting designers to create truly unique designs with a luminaire that can be designed to fit the room. Performance – LEDs are directional, reducing the need for reflectors and diffusers that and reduce efficacy. Aesthetics – it is often not enough to have excellent performance; this needs to be matched with stunning design. However, LED Linear has a pretty strong offering in that department as linear lighting provides a massive amount of versatility for creating unique and eye-catching designs. Custom designs with corners, squares, long linear runs, direct/indirect light and custom RAL colours are just a few of the options available that make LED Linear an easy choice. Colour temperature – LED Linear lights can often offer a wide range of colour temperatures, flexible to meet the lighting environment.
A 3-slide series of pictures taken with and without a pair of MasterImage 3D circularly polarized movie glasses of some dead European rose chafers whose shiny green color comes from left-polarized light. Note that, without glasses, both the beetles and their images have shiny color. The right-polarizer removes the color of the beetles but leaves the color of the images. The left-polarizer does the opposite, showing reversal of handedness of the reflected light. Left-handed/counterclockwise circularly polarized light displayed with and without the use of components. This would be considered right-handed/clockwise circularly polarized if defined from the point of view of the source rather than the receiver. Circular polarization is often encountered in the field of optics and, in this section, the electromagnetic wave will be simply referred to as light.

Ketai Industries Lighting Co.,Ltd.,which is established in 1999 by Brother Daniel and David, has been focusing on the researching and production of the top level commercial lighting products for decades. As it does with all modern lighting, size is less about rules than about balance and proportion. If you’re installing a linear hanging light above a kitchen island, for instance, you’ll need to be mindful of its size in relation to the island, and the overall size and design scheme of your kitchen. Lights that are disproportionately large or small will distract from the beauty of the lamp itself, and diminish the beauty of all the other elements in the kitchen as well.

Architectural lighting refers to a type of lighting design that enhances the architectural features of a space. LED linear lighting fixtures generally enhance the sharp lines and edges of modern commercial and residential lighting applications.
