Generation of color images using white light as source

An optical assembly for generating a color image using white light as source, the optical assembly comprising:

• a light source array (LSA) comprising a plurality of broadband white light sources;
• a color filter assembly (CFA);
• and
• a control unit;
• wherein the CFA comprises at least two waveguides, which are adjacently and successively disposed, and at least three filters disposed between the waveguides and/or embedded within the waveguides;
• wherein each of the waveguides has embedded therein at least two optical elements selected from at least one dichroic mirror, at least one beam splitting component, and/or at least one mirror;
• wherein a first waveguide of the at least two waveguides is configured to have transmitted thereinto light generated by the LSA;
• wherein the control unit is configured to actuate light sources in the LSA according to three intensity maps, each of the intensity maps corresponding to one of three additive primary color (APCs);
• and
• wherein the control unit is further configured to individually switch on and off each of the filters and synchronize the switching of the filters with operation of the LSA such that, when light sources in the LSA are actuated according to an intensity map corresponding to one of the APCs, the CFA filters therethrough light in the corresponding APC, which is output by a last waveguide of the at least two waveguides.
