Dispersion Compensation Algorithms

Definition

Dispersion compensation algorithms are mathematical techniques used to counteract the effects of dispersion in optical systems, especially in the context of signal processing and transmission. These algorithms help maintain the integrity of signals by correcting for the distortion caused by variations in the refractive index of materials, which can cause different wavelengths of light to travel at different speeds. By implementing these algorithms, it becomes possible to enhance the performance of optical biosensors and other biophotonic applications where precise signal interpretation is crucial.
