For this experiment, the He–Ne laser is propagated through the 1951 USAF target and the resultant image is projected onto a white screen using the set-up presented in Figure S1 . Optotune laser speckle reducers remove local interferences and significantly reduce speckle noise in laser systems by dynamically diffusing the laser beam. Offering a compact size, integrated drive electronics, and vibration-less speckle reduction, Optotune laser speckle reducers are ideal for beam homogenization, 3D scanning, metrology, microscopy, and interferometry. Speckle reduction Several different methods are used to eliminate speckle, based upon different mathematical models of the phenomenon.

Laser speckle results in a noticeable decrease in output image quality and therefore, the success of laser display technology is dependent on the reduction of this effect. Laser Speckle Reduction based on electroactive polymers @inproceedings{Giger2011LaserSR, title={Laser Speckle Reduction based on electroactive polymers}, author={J. Giger and M. Blum and M. Aschwanden}, year={2011} } Optotune laser speckle reducers remove local interferences and significantly reduce speckle noise in laser systems by dynamically diffusing the laser beam.

The project of rotating diffuser has a simple optical structure and can be easily implemented. We propose a design for speckle reduction in a laser pico-projector adopting diffusers and deformable mirrors. This research focuses on speckle noise suppression by changing the angle of divergence of the diffuser. Moreover, the speckle contrast value can be further reduced by the addition of a deformable mirror.

Speckle reduction Several different methods are used to eliminate speckle, based upon different mathematical models of the phenomenon. [5] One method, for example, employs multiple-look processing (a.k.a. multi-look processing ), averaging out the speckle by taking several "looks" at a target in a single radar sweep. In addition to the above, more than three laser primaries could be used to further reduce speckle.
