摘要：
Sub-micron diffraction gratings have been used for two LED illumination applications. One is to create a transparent see-through luminaire which can be used to illuminate and read a paper document or e-book. A second is a light sensor that can be used in a feedback loop to control a multicolor LED lamp. Optical design and experimental proof-of-principle are presented.
