Electro-active polymer LSR. Optotune is the first to commercialize electro-active polymers (EAPs) in the field of optics. 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. 2018-09-26 In order to improve image quality, speckle reduction is required in laser displays. Speckle reduction can be realized by polarization diversity,, wavelength diversity,, and time-average of Speckle Reduction. Optotoune's laser speckle reducers are nothing else than moving diffusers.

This paper focuses on speckle suppression by the reduction of temporal coherence which is provided by the broadband laser light. 2018-10-23 · 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 Speckle is a well-known phenomenon that occurs when coherent laser light is reflected diffusely from an optically rough surface and imaged by an intensity detector with finite aperture, such as the eye. 1 1.

Giger and M. Blum and M. Aschwanden}, year={2011} } Through theoretical analysis the reasons of generating laser speckle, we use an optical scheme for reducing composite speckle in the three LCOS laser projection system. The project of rotating diffuser has a simple optical structure and can be easily implemented.

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. We propose a design for speckle reduction in a laser pico-projector adopting diffusers and deformable mirrors. This research focuses on speckle noise suppression by changing the angle of divergence of the diffuser. Moreover, the speckle contrast value can be further reduced by … 2018-10-23 In a laser projection display, the presence of speckle tends to mask the image information and therefore its reduction is highly desirable.
