polarisaatiokehiin
Polarisaatiokehiin, or polarization rings in Finnish, refers to a circular or ring-shaped assembly of components used to influence, generate, or analyze the polarization state of light. The term combines polarisaatio (polarization) and kehä (ring), and is used in Finnish optical literature to describe configurations where optical elements are arranged in a loop or around a common axis. The exact meaning can vary by field, but it generally denotes a modular or integrated set rather than a single fixed device.
A typical polarisaatiokehiin consists of elements that manipulate polarization, such as linear polarizers, wave plates (retarders),
Applications of polarisaatiokehiin span optics research, polarization-based imaging and microscopy, telecommunications, and spectropolarimetry. In laboratory experiments,
Because the term describes a concept rather than a single standardized device, the exact components and arrangement
