Abstract
A retinal projector system, comprising a coupling means, a spacial light modulator, and a tapered optical waveguide having an input side surface and an output side surface, whereby the input side surface is larger than the output side surface, the coupling means being configured to couple coherent light into the spatial light modulator, the spacial light modulator being configured to receive the coherent light and output modulated light modulated in 2 dimensions towards the input side surface, the tapered optical waveguide being configured to guide the modulated light received at the input side surface and reduce a size of the tapered optical waveguide towards the output side surface, without losing any information from the modulated light at the output side surface such to allow an image formation.
