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. We are working with a CW solid-state laser. Optotune has developed an Electroactive Polymer Actuator-based solution to move a diffuser and drastically reduce the speckle contrast of Laser beams: the LSR-5-17 (Laser Speckle Reducer). With its integrated miniaturized electronics for HV generation and motion control, the LSR-5-17 provides a compact 27 x 21 x 6mm solution with a simple 5V micro USB interface for power supply.

Optotune's laser speckle reducers are essentially moving diffusers with a unique method of actuation. Laser Speckle Reducers are compact for ease of handling and integration. They feature integrated drive electronics and provide vibration-free speckle reduction. The reducers use four electro-optic polymers, which selectively move each reducer’s central diffuser along the X and Y axes to form a circular pattern of motion.

They remove local interferences and reduce speckle noise in laser systems by dynamically diffusing the laser beam. Diffusing angles of 1°, 10° and 20° are offered. 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 a passion for technology, Optotune is your ideal partner when it comes to solving challenges where conventional optics fail.

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.

av B He · 2014 · Citerat av 66 — For speckle reduction, the SAR images were filtered using the 5 × 5 refined Lee speckle filter [29].

The model is in a good agreement with the measurements, and speckle contrast decreases with TIS, as predicted.

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 Laser Speckle Reducer (LSR), which is already marketed by the company Optotune, is one such device.

Laser Speckle Reducers remove local interferences and greatly reduce speckle noise in laser systems. This is done 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. 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.

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. 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 mounted in a thin steel frame.

The objective of the master’s degree thesis presented at the Institute of レーザ・スペックル減衰器. lsrシリーズは、レーザシステムのスペックルノイズを大幅に減少させる装置です。 Power Technology’s IQ7 laser speckle reducer is specially designed to reduce local interferences and unwanted intensity patterns, improving overall laser imaging quality. The IQ7 features emission angles of 1°, 10° and 20°, wavelengths from 405 – 808nm, digital or analog modulation, and an optional on-board microprocessor with software interface . Offering a compact size, integrated drive electronics, and vibration-less speckle reduction, Optotune laser speckle reducers are ideal for beam homogenization, 3D Overview. Optotune's laser speckle reducers are nothing other than moving diffusers.
