The restoration is based on different deconvolutionalgorithms, that permit the recovery of objects from images that are degraded by blurring and noise. In microscopy the blurring is largely due to diffraction limited imaging by the instrument; the noise is usually photon noise.
Huygens software is named after the Dutch physicist Christiaan Huygens who is perhaps best known for his argument that light behaves like waves. Since
wave diffraction plays a key role in the Huygens Software, it was named after him.
