The laser has been regarded as the potential illumination source for the next generation of projectors.
However, currently the major issues in applying the laser as an illumination source for projectors are beamshaping and laser speckle. We present a compact solution for both issues by using a vibrating diffractiveoptical element (DOE). The DOE is designed and fabricated, and it successfully transforms the circularGaussian laser beam to a low speckle contrast uniform rectangular pattern. Under a vibration frequencyof 150 Hz and amplitude of 200 μm, the speckle contrast value is reduced from 67.67% to 13.78%, andthe ANSI uniformity is improved from 24.36% to 85.54%. The experimental results demonstrate thefeasibility and potential of the proposed scheme, and the proposed method is a feasible approach to theminiaturization of laser projection display illumination systems.
