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. 3. Transmissive Laser Speckle Reducer STOT-LSR-5-17. The OEM version of our laser speckle reducer comes with a minimal housing and is available with or without drive electronics. The most important parameter is the choice of diffuser angles. Standard diffuser angles of 1°, 4.3°, 8.5° and 17° are available.

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.

USING HIGH RESOLUTION THREE-DIMENSIONAL LASER SCAN DATA . 2-D SIGNALS: APPLICATION TO SPECKLE REDUCTION IN SAR IMAGES .

The IQ7 laser speckle reducer from Power Technology Inc. reduces local interference and unwanted intensity patterns to improve laser imaging quality in machine vision applications such as beam homogenization, 3-D scanning, metrology, microscopy and interferometry.

Founded in 2008, we started out with our core technology of focus tunable lenses, which was inspired by the working principle of the human eye. Laser speckle reducers, 2D mirrors and tunable prisms are further additions to our product lines.

Reduced speckle patterns; Reduced coherence length; Purely electronic feature - no additional hardware With the optionally available speckle reducer, the BrixXHUB is ideally suited for laser wide field applications like superresolution microscopy or high-speed Coherent sources such as laser beams, exhibit a phenomenon known as speckle . Speckle manifests itself as a coarse granularity in a beam intensity pattern. For ２つの駆動方式があり、それぞれに特長があります。 1.

Optotune's laser speckle reducers are nothing other than moving diffusers.

2017-11-10 · Speckle Noise Reduction in Laser Imaging by Electroactive Micro-Optic Diffusers. High degree of coherence, on the other hand, accompanies unexpected background speckles across overall image so

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. The basis of this approach is a single thin steel structure that is brought into resonance by pulsing an actuating coil with current, which generates a strong reluctance force.
