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 .

The LS R-1000 series is fed with two control electrical signals that selectively move the central diffuser in x- and y- direction. Optotune's laser speckle reducers are the ideal choice for: Laser projection displays from cinema to pico . Head-up displays. Beam homogenizer. Metrology. Microscopy.

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. The compact driving electronics, assembled on a flexible plastic substrate, stabilizes the resonance frequency in closed-loop mode and includes an error signal.

Laser Speckle Reducers are compact for ease of handling and integration.

4 Dec 2012 Mark Blum, COO of Optotune, describes the principle of laser speckle reduction and demonstrates various examples. Transmissive laser speckle reducer. LSR-3000 Series. The LSR Series allows you to significantly reduce the speckle noise of laser systems.

This is ac-complished by using a bundle of fibers of different lengths. Each fiber length differs by more than the coherence length of the laser.

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. The compact driving electronics, assembled on a flexible plastic substrate, stabilizes the resonance frequency in closed-loop mode and includes an error signal. Optotune's laser speckle reducers can be taylored to your specific demands in terms of size, oscillation frequency or transmission range. Laser Speckle Reducer SK-11. When a coherent light source illuminates an object, speckle noise appears and degrades your important images.

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. The model is in a good agreement with the measurements, and speckle contrast decreases with TIS, as predicted. The XLR 960ix laser-scanner integration tests demonstrated a 30% reduction of the speckle contrast, which supports EPE improvements on the product as designed.

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 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. Laser speckle reducers, 2D mirrors and tunable prisms are further additions to our product lines.
