Laser speckle reducers, 2D mirrors and tunable prisms are further additions to our product lines. Thanks to our deep understanding of optics and mechanics and
Speckle artifacts degrade image quality in virtually all modalities that utilize coherent energy, including optical coherence tomography, reflectance confocal microscopy, ultrasound, and widefield imaging with laser illumination. We present an adversarial deep learning framework for laser speckle reduction, called DeepLSR (https://durr.jhu.edu/DeepLSR), that transforms images from a source 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. Laser speckle reduction with laser speckle reducer STOT-LSR-3000 & STOT-LSR-OEM 1. Introduction Lasers provide numerous advantages over other light sources.

Our STOT-LSR-4C speckle reducer has an aperture of 18.5x18.5 mm and is especially suitable for applications where high laser powers and large beam diameters are used. The diffusor is mounted in a thin steel frame. Speckle Reducers are used to reduce laser speckle for applications such as beam homogenization or 3D scanning. Edmund Optics offers lithium triborate (LBO) and β-barium borate (BBO) Nonlinear Crystals for the harmonic generation of lasers commonly used, including Nd:YAG, Yb:YAG, Yb:doped and Ti:Sapphire. 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.

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. Optotune Laser Speckle Reducers remove local interferences and significantly reduce speckle noise in laser systems by dynamically diffusing the laser beam.
Diffusing angles of 1°, 10° and 20° are offered, providing maximum versatility for a wide range of uses. Laser Speckle Reducers are compact for ease of handling and integration. 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 …

However, one of the main issues with laser light sources and the resulting image quality is laser speckle [6–8]. 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. Optotune laser speckle reducer. It has a frequency of 300 Hz, so it wouldn't work. Nanophoton SK-11 speckle reducer. It is well suited for lasers with coherence length of at most a few meters, mainly pulsed lasers.
