“Polaroid”的概念、定义、翻译、参考文献-科学参考

Polaroid

Physics

A doubly refracting material that plane-polarizes unpolarized light passed through it. It consists of a plastic sheet strained in a manner that makes it birefringent by aligning its molecules. Sunglasses incorporating a Polaroid material absorb light that is vibrating horizontally—produced by reflection from horizontal surfaces—and thus reduce glare.

Sunglasses incorporating a Polaroid material absorb light that is vibrating horizontally – produced by reflection from horizontal surfaces – and thus reduce glare.

Geology and Earth Sciences

The trade name of a plastic sheet impregnated with an organic iodide compound which strongly absorbs light in one vibration direction and allows it to pass freely in the other vibration direction. The compound, iodocinchonidine sulphate, was first discovered by W. D. Herapath in 1852 and was named ‘herapathite’ in his honour. In 1928 E. H. Land combined the compound with plastic to produce the Polaroid sheet. It is now used in the polarizer and analyser of all polarizing microscopes to produce plane-polarized and cross-polarized (see crossed polars) light respectively.
