Abstract: A device and method for spectral imaging of an object. A plurality of sets of narrow-band light sources such as LEDs are provided. Each set emits illumination radiation in a different narrow spectral band. Each set is activated sequentially to illuminate the object. Light reflected from the object or transmitted by the object is focused on a detector array to image the object. Narrower illumination bands are provided by dispersing the emitted light using a dispersive optical element such as a diffraction grating. Alternatively; selected sets or subsets are activated simultaneously with duty cycles that emulate a preselected spectral distribution. For imaging ocular fundus tissue, the illumination light is shaped into an annular beam by an appropriately shaped waveguide.
