Abstract
In optical filter systems and optical transmission systems, an optical filter compresses data into and/or derives data from a light signal. The filter way weight an incident light signal by wavelength over a predetermined wavelength range according to a predetermined function so that the filter performs the dot product of the light signal and the function.
Claims5
A neural network system, said system comprising:
- an array of processing elements, wherein each said element performs a respective predetermined operation on one or more input signals and outputs a resulting signal to one or more other said elements or to an output device;
- and
- an optical filter
- that weights the intensity of a light signal from an illuminated sample by wavelength according to a regression vector, wherein said regression vector corresponds to the combination of a plurality of weighted orthogonal components of said light signal, wherein each said orthogonal component is weighted according to the amount of data it carries related to the presence of a predetermined physical characteristic in said sample and wherein said orthogonal components comprise a compression of data carried by said light signal, and
- that outputs a signal corresponding to said weighted light signal to a said element.
