<p>An optical projection system (200) comprises a non-point white light source (101), a source lens (102), a source stopper (103), an optical means (104), a first, a second and a third arrays of M x N actuated mirrors (108, 109, 110), a beam splitting means (105) including a first and a second dichroic lens (106, 107), a first, a second and a third field lenses (112, 113, 114), a projection stopper (115), a projection lens (116) and a projection screen (117). Each of the field lenses (112, 113, 114) is located between each of the dichroic mirrors (106, 107) and each of the arrays of actuated mirrors (108, 109, 110) and is used for collimating each of the primary light beams onto the corresponding array of actuated mirrors and refocussing each of the reflected primary light beams from via the beam splitting means (105), and the optical means, and eventually onto the projection stopper (115).</p> |
