Multistrålskonvertering

Multistrålskonvertering, sometimes referred to as beam splitting or beam recombination, is a technique used in optics and photonics to manipulate multiple light beams. It involves systems designed to divide a single incident beam into several distinct beams, or conversely, to combine several separate beams into a single emergent beam. This is typically achieved using optical components such as beam splitters, prisms, or specifically designed photonic integrated circuits.

The primary applications of multistrålskonvertering span a wide range of scientific and technological fields. In optical interferometry, it is fundamental for creating and interfering multiple beams to measure minuscule distances or detect phase shifts. In telecommunications, it can be used in wavelength-division multiplexing (WDM) systems, where different wavelengths of light, each carrying distinct information, are combined onto a single optical fiber for transmission and then separated at the receiver. This allows for significantly increased data capacity.

Further applications include laser-based imaging systems, where multiple beams can be used for illumination or detection from different angles simultaneously, enhancing image resolution or enabling 3D reconstruction. In optical computing, multistrålskonvertering is explored for parallel processing, where information is encoded and manipulated across multiple light paths. The precise control over the number, direction, and properties of the resulting beams is crucial for the effectiveness of these technologies.
