4 Agenda •Introduction •Active speckle reduction with CW lasers (oscillating diffusers) The IQ7 laser speckle reducer is specifically designed to reduce local interferences and unwanted intensity patterns improving overall laser imaging quality. When projected on a surface, laser light is often diffusely reflected by rough points present on the illuminated surface. 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. Up to now the nearest solution I have found is reported in the paper "Low-loss high-speed speckle reduction using a colloidal dispersion".

Two innovative technologies are offered, each with its own advantages. A laser is focused on the end of a rigid fiber optic bundle. Using a small motor, we then rotate the fiber around the laser's optical axis. This provides a way of mode mixing from the splitting of single point source ( laser) into multiple modes due to transfer of fiber bundles through the fibers (spatial coherence reduction) and bundle rotation (temporal coherence reduction). Laser speckle reducers, 2D Optotune develops and manufactures industry shaping active optical components that allow customers around the globe to innovate. 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. Optotune laser speckle reducers remove local interferences and significantly reduce speckle noise in laser systems by dynamically diffusing the laser beam.

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.

Laser Speckle Reducer SK-11. When a coherent light source illuminates an object, speckle noise appears and degrades your important images. This phenomena occurs due to the coherence of the light and seems to be inevitable. SK-11 reduces speckle noise and improves your image quality.

When projected on a surface, laser light is often diffusely reflected by rough points present on the illuminated surface. 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. Up to now the nearest solution I have found is reported in the paper "Low-loss high-speed speckle reduction using a colloidal dispersion". 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.

The Laser Speckle Reducer (LSR), which is already marketed by the company Optotune, is one such device. To date, the key parameters used in its design have been determined purely experimentally by means of observation. 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 .

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.

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.

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.

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. 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 Speckle Reduction. Optotoune's laser speckle reducers are nothing else than moving diffusers.
