High-efficiency spatial color separation method based on fractional Talbot effect
Based on fractional Talbot effect, Talbot grating is adopted to realize spatial color separation with high light efficiency.For red and green colors, a two-step Talbot grating is optimized and the light efficiency reaches over 95%.The two-step Talbot grating is fabricated and tested.Experimental results show that the Talbot grating indeed has the good ability of spatial color separation.
