Abstract: A system and method are provided for spectral shaping of light from a broadband source using a linear spatial light modulator (SLM). The system includes an illumination source generating light including a plurality of wavelengths, a lens to collimate the light and an aperture to define its angular spread, a diffraction grating to disperse the beam by wavelength, and a focusing element to focus the dispersed beams from the diffraction grating onto a plurality of pixels of the SLM. The SLM is configured to individually modulate the dispersed beams by diffracting light output therefrom into higher orders, where a diffraction angle of output light is greater than an input cone angle of incoming light from the illumination source.
