Abstract:
1. An optical processor, the optical processor comprising: a reflective SLM, a dispersion device, and a focusing device disposed between the reflective SLM and the dispersion device, wherein the SLM has a two-dimensional array of controllable phase-modulating elements, wherein the SLM is configured for selection of controllable phase-modulating elements whereby two-dimensional groups of controllable phase-modulating elements are formed at chosen locations of the SLM; wherein the optical processor is configured such that, using the focusing device, light from the dispersion device is spatially distributed by wavelength across the SLM and within each of the two-dimensional groups, and wherein the optical processor is configured such that the two-dimensional groups of controllable phase-modulating elements display different holograms at the chosen locations of the SLM where said light is incident, for independently processing different wavelengths of said light corresponding to a central wavelength of said light for each of the two-dimensional groups.
