Laser speckle reducers (LSR) Overview. Optotune's laser speckle reducers are nothing other than moving diffusers. But the way they are actuated is absolutely unique. Two innovative technologies are offered, these being Electro-active polymer LSR’s, and Reluctance force LSR’s. Electro-active polymer LSR.

SK-11 reduces speckle noise and improves your image quality. The model is in a good agreement with the measurements, and speckle contrast decreases with TIS, as predicted. The XLR 960ix laser-scanner integration tests demonstrated a 30% reduction of the speckle contrast, which supports EPE improvements on the product as designed. FIGURE 5.

In addition to the above, more than three laser primaries could be used to further reduce speckle. For example, di erent direct-emission green laser diodes with slightly di erent wavelengths could be used. Although additional laser diodes could lengthen the total optical path, length is not as critical a dimension for picoprojectors as height is. Laser Speckle Reducer LSR-3000 Series Speckle noise from a laser-based system is reduced by dynamically diffusing the laser beam.

Speckle Reducer. Many times one wanst to illuminate an object with high intensity and even illumination. Lasers have the intensity but are too coherence and cause speckle. A way to get around this is to use the Speckle Reducer, SK11. This optical device is totally passive.

Since speckle arises due to the highly coherent nature of laser illumination, one means of improvement is to use sources with reduced coherence, such as the direct- emission green laser diodes under development by several manufacturers. However their approximately 2nm linewidth is insucient to reduce speckle to acceptable levels. Optotune laser speckle reducers remove local interferences and significantly reduce speckle noise in laser systems by dynamically diffusing the laser beam. Optotune's laser speckle reducer is the ideal choice for application in laser projection displays, beam homogenizers, metrology, microscopy, interferometry and lithography. Optotune's laser speckle reducers can be tailored to your specific demands in terms of size, oscillation frequency or transmission range - contact Pacer for details. Laser Speckle Reducers utilize four electro-optic polymers, which selectively move each Laser Speckle Reducer’s central diffuser along the X and Y axis to form a circular pattern of motion. As a result, the Laser Speckle Reducers adjust the laser speckle pattern to appear as a uniform distribution of light.
