ABSTRACT:
A light modulator assembly includes first, second, and third light modulators, with first and second dichroic mirrors. The first dichroic mirror is located at an optical pupil of said assembly and is configured to split a beam of light into a first component beam and an intermediate beam. The first dichroic mirror then transmits the first component beam to the first light modulator and reflects the intermediate beam to the second dichroic mirror. The second dichroic mirror is configured to split the intermediate beam into second and third component beams and to direct the second component beam to the second modulator and the third component beam to the third modulator. A third dichroic mirror is configured to receive the output of the first, second, and third modulators and to pass the output from the first, second, and third modulators to display optics.
