ABSTRACT:
A multiple source array for illuminating an object including: a reflective mask having an array of spatially separated apertures; at least one optic positioned relative to the mask to form an optical cavity with the mask; and a source providing electromagnetic radiation to the optical cavity to resonantly excite a mode supported by the optical cavity, wherein during operation a portion of the electromagnetic radiation built-up in the cavity leaks through the mask apertures towards the object.
