Optotune’s LSR-4C speckle reducer has an aperture of 18.5×18.5 mm and is especially suitable for applications where high laser powers and large beam diameters are used. The diffusor is … 4. SCANNING SPECKLE REDUCERS One method to reduce speckle involves scanning a beam on a diffuser rather than scanning the diffuser on the beam. This has been suggested by Peled8, and Figure 2 illustrates one way to incorporate a Micro Electro-Mechanical System (MEMS) mirror into such a design. The incoming, collimated laser beam passes through a beam Laser speckle reducers, 2D .

Optotune's laser speckle reducers are essentially moving diffusers with a … As the use of lasers grows in application areas such as 3D depth mapping and laser cinema, a fundamental property of lasers called laser speckle has taken on greater importance. Many companies have launched to commercialize new approaches for reducing speckle noise. 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. Laser Speckle Reducers are compact for ease of handling and integration. They feature integrated drive electronics and provide vibration-free speckle reduction.

An electro-active polymer membrane is internally fed with two electrical control signals that selectively move a central diffuser in x- and y-direction. The LSR-3000 series integrates fully certified drive 2018-10-23 · In images of gastrointestinal tissues, DeepLSR reduces laser speckle noise by 6.4 dB, compared to a 2.9 dB reduction from optimized non-local means processing, a 3.0 dB reduction from BM3D, and a 3.7 dB reduction from an optical speckle reducer utilizing an oscillating diffuser. Speckle Reducer for laser imaging, projection displays and sensors. A laser is often referred to as a device that emits a beam of light through a process of amplification. High-brightness lasers are used in the field of life science, material science, medical diagnosis, and precision engineering for high-speed, high-resolution optical imaging.

A diffuser is bonded to a thin elastic membrane, which includes four independent electo-active polymer electrodes that induce a circular oscillation of the diffuser in x- and y-direction. Laser Speckle Reducers. Optotune's LSR series of transmissive laser speckle reducers allows significant speckle reduction in laser systems. Local interferences are removed by dynamically diffusing the coherent beam.

Interferometry. Lithography Reluctance Force Laser Speckle Reducer Launched in 2016, the reluctance force laser speckle reducer is particularly suitable for applications that require large format glass diffusers.

Speckle is considered to be a problem in laser based display systems like the Laser TV. Speckle is usually quantified by the speckle contrast. Speckle is usually quantified by the speckle contrast. Speckle contrast reduction is essentially the creation of many independent speckle patterns, so that they average out on the retina/detector.

Two innovative technologies are offered, these being Electro-active polymer LSR’s, and Reluctance force LSR’s. Electro-active polymer LSR. 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. The in-line laser speckle reducer (fiber optical beam homogenizer, or De-Speckler) is an all-fiber passive component which can efficiently homogenize speckle pattern and reduce unwanted modal noise (striations, hot spots, and beam non-uniformity) within a multimode optical fiber, producing a stable output beam that has fewer speckle hot spots and more uniform energy intensity profile. Edmund Optics’ Laser Speckle Reducers remove local interferences and greatly reduce speckle noise in laser systems.

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.
