Latest Patents

Cheong's latest patents include an advanced illumination system designed to eliminate laser speckle and a projection television employing this illumination system. The first patent outlines an illumination system comprising a laser light source that emits a multitude of laser beams, organized into beamlets along various optical axes. Central to this system is a diffractive optical element, which spatially averages the laser beamlets. This process effectively removes the speckles generated by the laser beams, enhancing visual clarity.

In his second patent, he further develops the concept by including a configuration that utilizes multiple lasers to emit laser beams in a structured manner. The first diffractive optical element in this patent separates the laser beams based on wavelength and focuses them onto different segments of a secondary refractive optical element. The innovative design ensures that the plurality of beamlets is focused and superimposed, thereby spatially averaging the beams and eliminating laser speckle.
