1. An apparatus for projecting an image onto a display screen comprising:

  • a. an optical fiber configured to carry a laser illumination to a downstream end of the optical fiber;

    b. a projector head comprising;

    i. a light modulator driven by electronic means, wherein the downstream end of the optical fiber is coupled to the light modulator such that the light modulator modulates the laser illumination to produce an array of modulated pixels collectively comprising a first and second mode of laser light coming from the light modulator according to a control of the electronic means; and

    ii. an optical projection arrangement coupled to the light modulator such that the optical projection arrangement projects the array of pixels onto the display screen to produce the image; and

    c. a laser source unit for producing laser illumination, wherein the laser source unit is optically coupled and mechanically isolated from the projector head.
