Abstract
Some embodiments provide for a modular video projector system having a light engine module and an optical engine module. The light engine module can provide narrow-band laser light to the optical engine module which modulates the laser light according to video signals received from a video processing engine. Some embodiments provide for an optical engine module having a sub-pixel generator configured to display video or images at a resolution of at least four times greater than a resolution of modulating elements within the optical engine module. Systems and methods for reducing speckle are presented in conjunction with the modular video projector system.
Claims20
A modular video projector system comprising:
- a plurality of light engine modules, each light engine module configured to provide blue light, red light, and green light, each light engine module comprising:
- a light engine housing;
- a plurality of red laser diodes housed within the light engine housing;
- a plurality of green laser diodes housed within the light engine housing;
- a plurality of blue laser diodes housed within the light engine housing;
- and
- a cooling system configured to dissipate or carry heat away from the laser diodes, the cooling system housed within the light engine housing;
- a projector head configured to project video images;
- fiber optic cabling configured to receive light from the plurality of light engine modules and to deliver the received light to the projector head, the fiber optic cabling having a length that is at least about 3 m;
- wherein the plurality of light engine modules are configured to be mounted in a rack.
A light engine module for use in a modular video projector system, the light engine module comprising:
- a light engine housing configured to be mounted within a rack;
- a plurality of red light sources housed within the light engine housing, the plurality of red light sources configured to produce red light having a red central wavelength and a red spectral bandwidth;
- a plurality of green light sources housed within the light engine housing, the plurality of green light sources configured to produce green light having a green central wavelength and a green spectral bandwidth;
- a plurality of blue light sources housed within the light engine housing, the plurality of blue light sources configured to produce blue light having a blue central wavelength and a blue spectral bandwidth;
- a red light optical system configured to direct the red light provided by the plurality of red light sources onto a fiber optic cable;
- a green light optical system configured to direct the green light provided by the plurality of green light sources onto the fiber optic cable;
- a blue light optical system configured to direct the blue light provided by the plurality of blue light sources onto the fiber optic cable;
- a cooling system configured to dissipate or carry heat away from the plurality of light sources, the cooling system housed within the light engine housing,
- wherein the light engine module is configured to be combined with other light engine modules to provide a scalable light source for a projector head of a modular video projector system.
