Abstract
An example projector includes: a first light source to provide first light; and a second light source to provide second light. A spatial light modulator produces: first modulated light by modulating the first light; and second modulated light by modulating the second light. An image direction device directs: the first modulated light to project a first image having a first pixel position; and the second modulated light to project a second image having a second pixel position.
Claims19
A system comprising:
- a first light source configured to produce first light at a first time in each of a plurality of light cycles in an image frame, and a second light source configured to produce second light at a second time in each of a plurality of light cycles of the image frame, in which the first light source is OFF during the second time in each of the plurality of light cycles and the second light source is OFF during the first time in each of the plurality of light cycles;
- a spatial light modulator (SLM);
- and
- at least one lens configured to direct the first light towards the SLM to contact the SLM at a first angle and to direct the second light towards the SLM to contact the SLM at a second angle that is different than the first angle, the SLM configured to:
- modulate the first light to produce a first image;
- and
- modulate the second light to produce a second image, the second image offset from the first image, wherein the second image is offset from the first image by less than a pixel in a first direction and by less than a pixel in a second direction.

A system comprising:
- at least one light source comprising:
- a first light source;
- and
- a second light source offset from the first light source in a direction;
- at least one fly's eye array comprising:

- a spatial light modulator (SLM) coupled to receive the second light and the third light from the polarization rotator and configured to:
- modulate the second light to produce a first image;
- and
- modulate the third light to produce second image;
- and
- a birefringent element optically coupled to the SLM to receive the first image and the second image from the SLM, the birefringent element configured to transmit the first image and the second image.
