Abstract
A display system is provided that includes a spectral separator configured to separate multispectral light into a plurality of light bands, and a homogenizing element configured to homogenize at least one separated light band.
Claims23
A display device, comprising:
- a static spectral separator configured to refractively separate multispectral light into a plurality of light bands;
- a homogenizing element configured to homogenize at least one separated light band;
- and
- a plurality of dichroic mirrors configured to interlace the separated light bands.
1 more element
A method of making a display device, comprising:
- providing a light source;
- providing a static spectral separator configured to refractively separate the light from the light source into a plurality of light bands;
- providing a homogenizing element configured to homogenize at least one separated light band;
- providing a plurality of dichroic mirrors configured to interlace the separated light bands;
- and
- providing an image-forming element configured to form an image from the homogenized light.
3 more elements
A method of forming a projected image, comprising:
- generating multispectral light;
- refractively separating the multispectral light into a plurality of light bands by passing the multispectral light through a static spectral separator;
- homogenizing at least one separated light band;
- and
- interlacing the separated light bands using a plurality of dichroic mirrors;
- and
- forming an image using the interlaced light bands.
