Abstract
Described examples include a device having a prism cube having a first side and a second side opposite the first side, the prism cube configured to: receive light comprising a first color light and a second color light, direct the first color light to the first side of the prism cube, and direct the second color light to the second side of the prism cube.
Claims18
A prism architecture comprising:
- a first prism;
- a second prism;
- a third prism;
- a first dichroic layer between the first prism and the third prism, the first dichroic layer configured to reflect light having a first color, transmit light having a second color, and transmit light having a third color;
- and
- a second dichroic layer between the first prism and the second prism, the second dichroic layer configured to transmit light having the first color, reflect light having the second color, and reflect light having the third color.
3 more elements
A system comprising:
- a first spatial light modulator;
- a second spatial light modulator;
- and
- a prism architecture having an input output face, the prism architecture optically coupled to the first spatial light modulator and to the second spatial light modulator, the prism architecture configured to:
- receive input light having a first color, a second color, and a third color at the input output face;
- direct a first portion of the input light having the first color towards the first spatial light modulator;
- direct a second portion of the input light having the second color towards the second spatial light modulator;
- and
- direct a third portion of the input light having the third color towards the second spatial light modulator;
- wherein the first spatial light modulator is configured to modulate the first portion of the input light to produce first modulated light having the first color;
- wherein the second spatial light modulator is configured to:
- modulate the second portion of the input light to produce second modulated light having the second color;
- and
- modulate the third portion of the input light to produce third modulated light having the third color;
- and
- wherein the prism architecture is further configured to:
- direct the first modulated light towards the input output face;
- direct the second modulated light towards the input output face;
- and
- direct the third modulated light towards the input output face.
