Farnsworth

The Farnsworth is a type of electro-optical device used for measuring the polarization state of light. It operates by analyzing the light’s polarization—its orientation and phase—using a series of precise optical components. In essence, it helps scientists determine how light waves are aligned and oscillate, which is important in fields like optics, telecommunication, and material analysis. The Farnsworth's design allows for accurate, rapid measurements of complex polarization states, making it a valuable tool for research and applied sciences involving light behavior.
